We like the control and power of Square-X. The strings are also very durable for a poly.

Nevermind that the color scheme of the Terracotta blends wonderfully with my Radical Pro, but the amount of control and precision I get with this 5-sided poly is fantastic. It is not the softest poly in the YTEX lineup, but I almost prefer the pop I get from this string. It plays similarly to the ProTour as far as feel of the ball coming off the racquet, but add the bonus power and spin. The only thing I think ProTour has the edge on PentaPower is the tension maintenance. Protour definitely has the edge there. I tend to restring my sticks every 2-3 weeks anyway so that has not been an issue for me. So if you want an all-around high performance shaped poly, I can not say enough good things about PentaPower. RIP the Terracotta variant.

I have used many strings in my 40 years playing tennis. I am a 4.0/4.5 player and I can say without a doubt these are the best strings I’ve played with yet. I strung them at 58/54 lb tension and I can feel the ball extremely well. It’s amazing what strings can do to your game. I have recommended these strings to every player I know. Try them once and you will never go back to what you use.

Great string/good feel/ easy on the arm with the right tension and mechanics✔️🎾

the rope is excellent my first experience with YTEX I'm gitan a lot

I now have the white, blue, and red Dri-fit shirts and love them!!! Quality short at a good price; and, I get to answer questions about “what is YTEX?” when I play tennis!

Just wish there were more color options in stock for a size medium!

This was the first YTEX string that I fell in love with. Great spin, control, and power. I just put this string in a client's racket for the first time. He loved it!!! I am torn between this string and the Triangle Twisted Purple to use in my personal rackets. I will have to keep debating with myself over which of these awesome strings is the best for my game. I am a solid 4.0 all-court/baseliner that hits a very heavy ball on both forehand and backhand. I feel like this string gives me just a little more spin than the Triangle Twisted Purple.

I was pleased with these strings, but I need to give them another playtest at a lower tension. I originally strung my racket at 55lbs, will be playing with these strings at 46 lbs in the next few days. I will update my review then.

Played with this string one time with tension at 55 lbs. Was not a fan. Followed the suggestion of Ivor and lowered the tension to 46lbs. This is now my personal choice for playing. Great bite, awesome control, amazing easy power. I will continue to use this string until I find another YTEX string that I love more. It is a really close race now with Triangle Twisted Purple and the Hex-X Red, both are amazing strings. I have had no arm problems playing with this string. YTEX strings are some of, if not the, softest co-poly strings available.

Soft material, cool logo on the sleeve, and it dries quickly. Love it!

Super shirt , Cool, durable and fits perfectly can't beat the price point. I will buy another. Thanks Ytex.

These strings played great and gave me alot of spin. They did start to make my elbow hurt, but I'm not young and play 5 times a week, so I need to stay away from co-poly strings. But people who love and can handle poly, will love these.

I really like these strings! They play very solid and are really durable and have a great feel! They also helped my elbow pain go away. I've had some with Co Poly strings, but I don't have pain with these strings!! Highly recommend.

These strings are great! They have made my elbow pain go away! I had pain with the Co-Poly, but these have fixed my pain. They also play great and feel solid. They are very durable as well.. You will get many matches out of them.

excellent string!
