For the money you can’t beat the value. These strings play well and are durable for the price. They're great if you use them as a cross string with a desired main string. I am using them with Wilson Sensation 17 as a main string for a soft, arm friendly feel. Work good for me.

A solid responsive string, especially in the 17 gauge.

Racquet = Head prestige MP Main string = Tecnifiber sync 16 G ( 54 LBS) Cross string = Prince XC 15 L ( 50 Lbs) Player age = 11 years old boy| usage hours = 2 hours for each use for 5 days As you can see, my tensions are low and "gentle" use. Yesterday it broke on my string machine while I am putting on 52 LBS. I might be getting the defect one.

SOFT AND EASY ON THE ARM. ALMOST GUT PERFORMANCE.

Great Quality, lower price & On time shipping

I use this as part of a hybrid bed to complement a good syn gut. It's lively and easy to use in my stringer and has good longevity.

Biphase 16G ... Good feel and pretty durable. Much easier on the elbow as advertised. My string of choice from now on

This is a great string. It looses tension quick so I would account for that in the stringing unless you are going hybrid or per-streching them

Great string in every respect. Very good feel and more durable than you would think for 18g. Better than gut in installation and over all production.

I use NRG2 18g in the crosses with Pro Supex Big Ace Micro (19g) in the mains and it provides me with a silky smooth blend of power, control and playability I haven't been able to replicate with any other multi - including Biphase. Compared to Biphase, NRG2 feels more plush and doesn't require the break-in period the former requires. It's silky smooth from your first stroke and when it settles in, it's so nice. Durability for my setup, despite the thin gauge, is pretty impressive in my POG 100's with a 16x19 pattern. Love this stuff.

About 15 years ago I tried many topspin strings and settled on Prince topspin. Then I discovered the Duraflex (PTD) version and it lasts twice as long -it's very forgiving and generates power when you have to. The string gives me good bite on the ball and gets it over the net but in the court. I've tried other hot-shot strings that the 'pros play with' that gave me more power but no control and also can't stand the metallic titanium feel - the guys who recommended those 'power' strings all have shoulder problems!. So back to PTD and all's well. Just ordered a dozen packs for the year.

Great power, exceptional response, durability. I am a believer in this string, the first Tecnifibre string I've ever used.

this is a great string; it plays like gut; however, it does break too easily

It won't, but a very nice string.. I am a low tension player and get good life and bite from the 17 gauge. very similar to NXT.

I've been using this string for about two years and love it. I install it in a stiff frame at 45 LBS which gives a soft feel and great power. Furthermore, this setup gives great touch.

Excellent feel and control, along with comfort and good spin effect for Spin configured racquets. Used in Hybrid configuration with poly on the mains.

The racket has strong durability and maintain tension after a good a period of playing time. Like the control and spin created by the 17g string.

Just bought. Looking forward to placing this gut like string in racquet!

Awesome feel, if you want to "punch that volley" and want a "drop it like its hot" dropshot, that keep your oppnenent scampering...Look no more! Been using x 5 years and no tennis elbow ever! Mean sting...for mean pinpoint shots!

Researching a bunch of strings and differences - went with this based on reviews and price - and I couldn't be happier! Will definitely restring with this when the time comes. Strung the Duraflex on 2- Prince Tour Pro 98's and we are very happy.

I love this string! It has long life and helps to generate power and bites the ball for spin too.

Very good over all.

Very crisp feel and unrivalled amount of spin. I always put these in the mains. They will saw through any main as a cross very quickly. I don't string it any higher than 55 pounds to avoid tennis elbow.

Good strings for durability and comfort.

with this string you can feel the power of a shot and do not loose the touch for drop shots or slicing. also when loosens it breaks fast . definitely will recommend

Perfect all around string for string breakers. Thinner gauge for better play and tension maintenance.

Great string aside from the expensive price. Has good power and feel but durability is just ok (typical for a multifilament). I use at as the cross strings with a poly in the mains.

I have so much more power with this string but didn't lose any of the touch for drop shots or slicing. Will be using this exclusively from now on

This is the best string for feel and spin that I have ever played with. Very responsive and with a 16X18 string-patterned racquet, it gets great bite. For an 18 guage string it has very good durability.

I bought Ashaway Kevlar 360 ft Reel Tennis String Size: 16g. Excellent string to combine with multifilament like NXT.

Excellent tennis string at a great price for poly.

decent string for the $. easy on the arm. good durability.

Terrific string and arm friendly. The natural seems a bit softer than the black. I prefer the natural. String at mid + 2 or 3 for a great feel. My string of choice. The 17G also has a bit more feel than the 16G. Best multi I have found. My other half now uses it and prefers it over a Babalot Natural Gut / Luxilon ALU power Combo. I am a 3.5 player. Swing away!

This string has given me good control and spin. I use combined with Luxilon for power with good results. Great value for the price!

Love this string, have had elbow problems for years, only string I have used that has helped relieved the soreness. Also had to change Racquets. Best Racquets are Prince.

For the price, this is the best multi-filament string on the planet. Great feel and durability is better than expected.

This is my go to string. It balances between spin and durability.

Prince Syn Gut 17G is a great buy. I hit flat with a head light racket and this string feels soft and provides great control when strung at 58 lbs. I wouldn't say that the playing properties last as long as other more expensive strings or that it provides maximum power but you can't beat the price and it will relieve some of the stress on your arm produced by stiffer strings.

I love this string. I usually string my racquets with poly mains and Gosen Proform on my cross strings, and o love the durability and the feel. It is a very good string to string and for the money you can't beat it. I string a lot of the guys I play tennis with during the week of all levels, and they love it. I have used this string for at least ten years, and I have nothing bad to say about it.

Let's start with the positive. This string has great feel and control. It gives me a feeling of being in complete control all the time. For power, I would give it an average mark and same for spin. The 17 gauge strings definitely get more bite than larger strings, but not sure it has a lot to do with the string itself. I would recommend these strings for older players that play a placement game.

After a few years of hitting w/ polyester strings (RPM Blast, Tier One Firewire), I contracted tennis elbow. As a result, I switched to the X-One BiPhase strings. Very soft, gut-like string. Xlnt for arm pain. Nice touch. But nowhere near the power and spin of poly. That's the trade-off. Would likely be good to mix w/ a soft poly in a hybrid fashion.

The best synthetic gut tennis string which I have played

use as hybrid with Luxilon Savage Lime, 50/55 in Wilson BLk 95 racket. Great feel and power on ground strokes, serve and volley

Very responsive string on my Prince Hybrid Hornet, however with topspin strokes, doesn't last long as with most multifiliments.

I had tennis elbow for about a year, but i never wanted to stop playing. This string was the easiest on my arm. It also gave me the playability i needed.

I give it 8 out of 10. Tested 17g. Playability 9, power 7, comfort 6, durability 10, topspin 7. Good strings however behave way better at tension under 56 lbs (would recommend 48-52 lbs)

I love these strings especially combining them with a poly it lasts long and plays great!

used in a prince shark mp. powerful and easy on the arm. great service from midwest sports.

It looks cool. It works good. The package it came in looks cooler then the one on the picture.

Gosen makes a quality made in Japan single core synthetic gut comparable to prince synthetic gut and other well known synthetic guts. I use it as a cross string in a poly/synthetic gut hybrid. The white version is a bit stiffer than the natural colored one. So if you prefer a softer string, get the natural color. I get a bit more spin on my serve using the 17 vs the 16 gauge.

Great string if you have arm issues & still want power.

Super string for the masses great playability very durable great feel and feedback...try bi-phase and nrg together for the ultimate

I use this string a lot when stringing rackets in our retirement community. It is my string of choice and plays very well for senior tennis players. The quality and price of this string is great.

My stringer recommended Tecnifibre TGV when I was experiencing some arm issues. It's a very comfortable string. And I am also impressed with the durability.

This string is one of my favorite multi string. I often switch to poly/syn gut (multi) set up depending on my arm feeling. When I need to go back to multi/syn gut set up, this string is the choice for main. It feels crisp and flush!

I use this in my crosses with Pro Red in the mains great combo. Plenty of power and control only these strings do break after about a wk to 10 days of play.

Provided longer play time than expected. Good grip on ball provided better control of shots

This is my first ever reel of strings. I'm a cheapy, so this was a great value. I strung a full bed on my friend's Prince TT, and he said it felt good. I've read that a hybrid would work better, so I'm looking forward to doing that on my Gamma Tour 320x. Great racquet btw.

Love the price for a quality string that lasts a while.

Like these strings, which to me are comparable to the Wilson NXT but at a better cost. The sale is even better! I like to be able to feel the ball on my strings.

Solid all around string. Not hard on your arm like a poly and much more durable than the multifilaments.

Prince Syn Gut with Duraflex is the best synthetic gut available. I have strung many racquets with different types of synthetic and this one definitely lasts the longest and is the perfect combination with a polyester string. I use it for all levels, from beginners who string their whole racquet with this, to highly competitive players who use a hybrid.

This string is a bargain for the price. It won't generate the spin of a poly but it plays quite well and has good durability. It also makes a nice choice for hybrid set-ups.

great string if you have a tennis elbow... tears quickly though if you play with a lot of top spin

This is the best string I have ever had on my head radical mp. You can apply as much top spin or slice from the technifibre black code as needed. It gives you some extra pop on your serve as well. I will never switch away from it to even try another string.

I bought this reel solely for the purpose of using it as a cross string in a hybrid with a poly. They work great and I wouldn't hesitate to use them with any polys. I also use them for my customers who don't prefer a specific synthetic gut in their racquet. They are cheap, and very efficient as well! Great buy.

I have been loyally using the PSGD since long ago. I absolutely love the feel of the strings. One thing though, is that they don't last as long as I thought they would. However, for the cheap price, you can't beat it.

Good string for the price. Soft feel.

Black code & luxilon are my two favorites... use in my 325... Tipsy endorsed this one last year and now I think Razor code... Although a little less bite than ALU Rough... it holds tension much longer. Love Tecnifibre

Awesome strings.

Love this string...easy on the arm, especially for a poly. String Aeropro Drive at 58 to 61 pounds

I love these strings. Used them for years.

My son is 11 and plays with this string because of the playability, control, power, and most importantly arm friendly qualities of this string. It does fray and break faster than any string I have seen. But, it is so well worth it. My son gets about 20 to 30 hours before they break. I used to only use poly string and after buying a stringer to keep up with my sons string breaking, I tried it. Wow, I was so amazed. First, the serve. Spin, check, placement, check, power, check. Groundstrokes same with the added touch of being able to drop or lob. Net was also better with angles and just great pop. I highly recommend any serious player to try this string, and you will see all of these instant improvements. Unless your Nadal, which I assume you are not, stick to this multifilament and stay away from poly.

I use it to restring racquetball racquets and is very durable and playable.

I like it because it is cheap and has some good feel.

Good durable string that works well as a cross string when paired with a firmer (RPM, Crossfire, etc.) main string.

I like the feel, comfort and power combined with this string. Easy on my arm and elbow. It helped improved my game and produces a lot of spin. I used it for my Babolat Pure Drive French Open Racket. Definitely I would recommend it to anybody who wants to improved their game.

You can't fairly rate a string unless you consider how much you pay for it. This string is an awesome value. A 660' reel for $17 ???? Are you joking. I've been using this string as my "base" level string for my customers and everyone loves it, considering the price. Sure, there may be players that "think" their game deserves more, and maybe that's a valid point for some. But this string is every bit what most people need.

Likes: Price, best string I've ever used, looks, they don't break easily Dislikes: None I've used pretty much every main brand string (RPM, Luxilon, Head, Solinco) and I fell in love with this string. It allows me to hit big, but the spin potential is high. It plays well with every shot.

Used this as a median or middle-of-the-road string to see what characteristics players want on their rackets, e.g. Firmer, softer, durability, etc.

Although this string is very stretchy, it is very powerful, long lasting, and easy on the arm. I string it at 45 lbs, ala John McEnroe.

Good power and touch, but not as durable as other multifilaments I've used. I prefer the Kirschbaum Touch because of $$ and durability. Good cross string for a hybrid (ie 4G or RPM Blast)

I've tried out all kinds of multifiliments (nxt, sensation, nrg2, silent partner) and none has the feel of the biphase. I think it actually has better feel than even a nat gut (Wilson). I have used 18g biphase both in a hybrid and by itself. I loved the feel of it by itself, but durability is a problem. One set I had broke 3 games into a match. So now I use it with black code 18g in a hybrid and I love it!

I have tried all kinds of polyesters (luxilon, Wilson, babolat), but the Black Code is my favorite. I use 18g, so that in combination with the shape of the string makes for big time spin in a hybrid. Its also the softest polyester I've played with, so its great for preventing arm/wrist problems. And it seems to have adequate durability. I'm sure a 16g holds up longer, but I play 3+ times a week at a 5.0 level and might break 2-3 per year. Most of the time the crosses of the hybrid break first. Excellent string- a little pricey, but its worth it.

Put this string in a few friends racquets as well as my own. Everyone loved the control.

best synthetic tennis string ever, perfect feeling and touch

Looking for control like NXT but was popping strings every 2-4 hrs. Didn't like Big Banger or RPM as lost feel- like Head Gut PPS for pop and control, but needed to switch when I was playing 6 hrs/day as was breaking around 10 hrs. This has endurance (14 hrs) and control- lose some power compared to the Head, but I didn't need.

Read online reviews, seemed to get very positive ratings. Have only tried it once but seems like a very good overall string.

Great feel. My favorite string.

The string is an excellent value and plays very similar to the gamma synthetic gut, but at a lower price. The lower cost does allow me to play around with string tensions without worrying too much about price. I also string my own rackets, about 1 per month, I play about 3 - 4 times per week.

Love this string. Been playing Prince Syn Gut 17 for over a year now but just switched to the Lightening XX. Same great feel with a bit more pop. And I love supporting the breast cancer foundation with the fun pink color.

I've used this string for 8 years, and every time I try another string, I go back to it. Natural gut feel at an affordable price. Much more forgiving on elbows and wrists than poly strings.

Comparable to most of the top of the line multifilaments but at a reduced cost. Very soft and elastic. Tons of power, soft on the arms, but will not last very long. Overall a great string and worth trying.

I tried various types of strings since I started to play tennis. I had tried the super expensive and the relatively inexpensive strings. The Prince Syn Gut is by far the best strings. I mixed this string with the Tecnifibre strings to get the power and touch combo that many intermediate players like. For $5, y ou can't go wrong with this.

Seems working fine. First time using this string. Nothing I don't like so far.

Prince Synthetic Gut Duraflex is a great all around string. It's a tried and true classic and every stringer should always have a reel in stock. Works great in a hybrid or in a full bed.

I string a lot of rackets for folks in my area. This is the most requested string even with all of the new string types available. It is very easy for the stringer and very durable and predictable for the player.

Lasts at least 4 rounds of 2 hour play. Feel is excellent. Super comfort. Not overpowering. Dumped poly due to shoulder pain, but even without the shoulder issues I would have made the switch back to a multifilament, and this is at the top of what I've tried. Tried the 17g and 18g, 18g wins for spin. Groundstrokes are pinpoint, volleys are solid. I'm a big hitter, with lots of topspin.

I am on the court 4+ times a week, and these 17 gauge strings have relieved my tennis elbow. I am on my fourth set, and they last about 2 - 3 months.

My daughter using this string in the crosses with the Luxilon 4G 16L mains. Great Hybrid combination with power and control.

I bought these strings because of a good word from a friend of mine. They are very easy on the arm. I use the Prince O3 White racket and have a medium swing speed. With these strings, I serve effortlessly and when volleying, I have total control. The only thing that would make these strings better is if they lasted longer. I've had them for 2 weeks and play constantly and they're almost done. But, overall, I would certainly recommend these to any player.

I like this sting. I have a lot of arm issues and the string is soft enough to be easy on my tennis elbow and shoulder. It wears quickly, but that is to be expected, I guess to get the playability.

Tried 17 gauge first: strung at 60, but not enough pop on serves and strings broke too soon. Switched to 16 gauge at 55, plenty of power and excellent spin. Most importantly, no more sore elbow or shoulder or wrist, gone because of the soft, gut-like feel of this superb string. Buy it!

I use this string exclusively. Great feel, spin, and control. I definitely recommend this string to anyone looking to upgrade from a standard synthetic or something like a Wilson Sensation.
