I used this string for the first time.
My racket is Angell's 97 320g. The tension was set at 45-43. The stability and milding sentiment were good.

I strung at 45, had almost no break-in time. I swing thru completely and the spin pulls that ball down. I really love this Quadro Twist string.

I got my YTEX Dri-Fit shirt with the starter box. The shirt expels moisture quite well, looks and feels great. I will buy more shirts and the Dri-Fit jacket for our cold winter season in Finland 😀🎾

Ivor was correct, the black is a little more comfortable compared to the white. I have been on a string journey for over a year testing many strings. I was searching for a comfortable poly with power, feel, some spin and control. The Square-X Black is it!!! This string paired so nicely with the new Pure Drive standard which I strung at 51M/47C. It has also been very nice in the 2020 Wilson Ultra 100. These are both stiffer racquets and these strings balance that out with out taking way the crispness. Will be ordering a reel.

Of all the strings I've played with there are few that come close to the Quadro Twist. It is the best soft poly that I've played with and intend to completely to switch to this string on all my rackets. Its spin gives be good control when going for power shots, but that also provides safety because of the rpm's you're able to put on the ball. Very beneficial for any player to try!

Strung at 51 in Graphene Prestige, great spin, serve pop, and control. Soft on the arm.

The Quadro Twist Black string is an excellent string for putting spin on the ball with lots of power. The Quadro Twist Black string is very comfortable to use. The string makes a "twangy" sound when hitting that some players may not like. But, the string performance is hard to pass up.

The purchasing experience was terrific as the owner/CEO personally assisted me in making my purchase of the Quadro Twist Black string reel during a time when availability of the string was in short supply.

Perhaps having different sizes of the string (e.g., 17 gauge, etc.) might be more attractive to people that tend to use thinner gauge strings.

I really like the Quadro Twist string. I used the Black for my Main and White as the Cross strung at 54 lbs that I strung myself. I used my newly strung racket this weekend and was very happy with feel and how it played. Being a weekend warrior I'd like to see how they hold up over some more playing time. I know I'll be using this string for some time.

Love this shirt

5 star!!!! Best strings I have ever played with in my 40 years of tennis !!!

Love love love the hex!!!!

My high school tournament players love the feel and durability of theses strings!!!

I tried Octo Twist for the first time. Not as soft or powerful as Quadro twist or Square X, But still comfortable. I just strongly a couple pounds looser than normal and I was able to get my normal pop on the ball. As usual, YTEX didn’t disappoint!

At first I was very skeptical about this string. I strung one of my student Yonex racquet at 47 lbs. After a couple of hours the string started to kick in with power,durability, spin and not forgetting the feel. I'm looking forward on getting more reel. Aloha

This is my favorite YTEX string! Far and away the most comfortable co-poly I’ve ever used. Super lively with lots of pop. It spins well but where I think it really shines is how well suited it is to my serve and volley game and flatter strokes.
