All the tournament juniors love this string. Durability is good. My one complaint is the price for 600ft and still paying for shipping.

I reordered this string for a customer that I strung his other racquet with. Loves the string.

I've sampled most of the YTex line of polyester strings and Penta Power Twisted has to be my favorite one so far. It has a slightly crisper feel than the other strings which I prefer in my Yonex VCore 95 racquets (strung at 45/43 on an electronic constant pull machine). It provides a clean response and impact feel while also allowing for exceptional spin generation. I'm able to hit heavy shots from the baseline while also using spin to create short-angle shots from the mid-court. It also handles touch and finesse shots beautifully. Durability has also proven to be great as I'm easily getting over 12 hours of hitting from each stringing.

This is definitely one of the better poly strings on the market at the time and I would highly recommend it.

Just recently play tested the SINTEX paired with PRO TOUR BLUE. This multifilament string is better than any other multifilament I have used. Balances out the spin of the poly, giving it even more feel, without feeling to soft or mushy.

I love all of the YTEX strings, but this one is my favorite by far for hybrid set ups. Has great bite and power.

This string is bought specifically for one of my clients. She loves the power, spin and durability of Square-X

I have been a Square-X full bed black user for years...Prince Warrior 107T at 45 lbs. Looking for something "unique" I decided to string up the mains at 48 lbs with the black, and use the Square-X white in the crosses at 42 lbs...WOW! Love, love, love the way it feels! I had hip replacement surgery 4 weeks ago so I cannot wait to really give this a go..great job YTEX!

I teach at the largest indoor facility in the EU - Tali Tenniskeskus. We have 22 indoor courts each court has ample space for running to the ball. Imagine what li is like to keep the club warm? During the winter it gets a little chilly inside, my YTEX Dri-Fit jacket keeps me warm and dry. Any condensation in your garment will result in a loss of body temperature. This Dri-Fit jacket stays dry therefore you stay warm 😀🎾

I was hesitant about switching to these strings, but I got them and I love them. I can’t play with anything else. They are so easy on the arm and strong enough to get some pop.

Wow, these strings are a perfect match for a weighted Blade 100L. The flex on the Blade has an RA of 69 and it feels it. These strings really smooth that out and offer up a little extra power. These strings also increase the spin potential and help take full advantage of the 16 x 19 string pattern. All of the Ytex strings have above average longevity and I know these will be no different. I have used these strings before in a 2021 Yonex Vcore and felt they were a little too muted. In the stiffer Blade they are perfect. I would say these strings would be ideal for stiffer racquets like a Pure Drive and Wilson Ultra. Did I mention the color which matches very nicely. Will buy more!!!

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
