Really been enjoying these strings in my Babolat Puré Aero Plus. They give me a little extra power, nice spin, & super durable. Tried the 2nd time round at 48lbs instead of 50lbs which is the sweet spot for me. Had been using Solinco Tour Bite, but like this string much more!

I finally got the YTEX hat(s) the white and the black in time to wear to the Kansas State 3A Tennis Championships in Wichita, Kansas. YTEX has become a growing phenomenon here in Kansas. The Square X Sharp string made an appearance. I received several comments about my hat and the strings. Keep up the good work.

Felt a little stiff at first but after a little bit they were fantastic

Great quality and look and best of all keeps the brand visible to my players.

Easy to install, stay in place, effectively dampen vibration and look great.

Microfiber Mains, Square X Sharp Crosses. So far so good. Microfiber offers nice feel, comfort and power. The sharps are providing good stability to help with the spin and control. This is one of my favorite hybrid sets using YtEx strings.

Easy to put on and does a great job limiting the vibrations on my elbow.

Had a student order a new racquet from TW and request Square X. He actually wanted Square X Sharp but did know how to specify. Upon receiving it he tried it and said I like these strings just as much! He plays a CIF match this week and betting he does well with his new setup! HEAD GRAPHENE 360 Plus w/Square X White.

In my first few years of tennis I have not played with many different types. I started with a natural gut, progressed to a Wilson Twist/Solinco Confidential, then Solinco Hyper G and now the Square X.

I play with a good amount of top spin and after several weeks of hitting , I am generating more top spin with the Square X. Where I see the most improvement is on my backhand slice. There is much more bit on the ball. At this time I plan to continue with the Square X. Great product and you customer service is outstanding.

The strings def have shape, they def grab the ball!

Quattro twist white strings offer a lot of spin, to a noticeable degree. With that said, I found a lot of my shots flying long due to the power of this string, and control was also hard due to the launch trajectory I am not used to and am not a fan of. These strings were a big pain to string, so much coil memory and lots of stretch. Also the shopping experience became painful with so many automated follow up emails, some obnoxious. When I would write an email inquiry it did not get the same enthusiasm and the speed of response was not great

Perfect fit between the strings keeping a tight hold avoiding bouncing out on a mis-hit.

I Love how easy it was to string!

So far I’m really enjoying the Square-X Sharp strings. I have it strung on my Diadem Elevate Tour - 52lbs on the mains and 50lbs of a multifilament on the crosses. I am getting a lot of spin on my ground strokes and love the feel on my volleys. I will continue experimenting with these strings and likely do a full bed for the next stringing. Great job YTex!

I bought the strings to improve on spin. I have notices significant improvement in spin with square x strings. Especially while serving, it a game changer.

I strung my ProKennex Ki Q+ Tour (315), 98 sq inch racquet with a 16 Gauge (1.30mm) multifilament in the mains at 52 pounds and the YTEX ProTour Blue (1.20mm) in the crosses at 50 pounds. This string set up allows me to have comfort, control, spin & power. I was able to practice on the hitting wall at the local park for a solid hour with no pain. I used this racquet and string combination when practicing with the ball machine, and my shots from the baseline were deep and controllable, and landing inside the opponent's baseline with about two feet to spare. These strings are very comfortable and pockets very well. Pick your target and hit it. I highly recommend YTEX ProTour strings to anyone suffering from tennis elbow, and this is coming from someone who had non-surgical treatment with plasma injections to repair the damage done to my tendons in my elbows from 24 years of military service and unrelated to tennis. I was very particular and cautious when experimenting with various tennis racquets and string combinations with the goal of playing tennis pain free. I string my own racquets, and I liked the ProTour Blue (1.20mm) so much I bought a reel because this will be my go-to co-poly. In the summer months when the temperature gets into the mid-90's, I will try the YTEX ProTour Orange (1.23mm).

These dampeners are great because they cover the two major problems that most dampeners face. For one, they actually stay on the racquet with the occasional frame and don’t fly off where you will never find it again. Secondly, they are made of soft rubber which is something many people overlook. If the rubber is to hard, the dampener feels like it is not actually there. I personally hate the sound of having no dampener, which some of the dampeners i own do not fix. With these, there is no sound or vibration but you can still feel the ball on the strings.

I’ve been using the quadro twist strings for about two years now. I had originally switched from rpm blast but needed something softer due to a shoulder injury. These strings are great as they are softer than standard poly but rigid enough to last a good while and give control and spin. Another good thing is that they do not seem to lose their pop after being strung for a while and they can actually be strung fairly tight but will not feel stiff. I currently use the quadro twist at 55lbs mains and 57lbs crosses in a babolat pure aero rafa racquet.

Used it for Babolat Pure strike found it not lively compared to the Technifibre racquet!

It has a really nice launch angle and offers a really crisp bite into the ball, while maintaining control and giving the ball plenty of plow through when it impacts the court it has been my favorite string to put in my mains since I got my first reel of it shortly after it came out I put it in my “Pure Drive” my “v8 blades” and now I have been loving it in my Wilson Shift! Also I love the fact that it is an 18g string allowing for a nice light and maneuverable feel!!

Good feel and performance at higher tension. Or easy power for beginners!

Similar to Hexagon X black. Good spin, nice control, stiff recoil. Beauty and braun!

Estimate range between 15% to 30% more spin. My guess was 20%.

Great feel, great control, superb trampolining!

Solid feel on hits with good spin and superior control!

I always use them and like to hand out one for customers to try!
