works for me
This shopper rated the product 4 out of 5 stars

I've been using the TNT 17 for about a month with no complaints. I wanted to try it because of tennis elbow and it seems to be less impactful. Time will tell. I just read the other 16 reviews posted and only one was more recent than 2016. What's going on?

Great Playability - Excellent Value!
This shopper rated the product 5 out of 5 stars

I got a set of Gamma Syn. Gut 16g with the X-ST stringer I bought from Midwest Sports. Truth be told, it sat in a drawer for months until I decided to string it in a 14 yr. old Pure Control Team I keep at my in-laws. It sat over there for a year after I strung it before I took it out during a visit. I have to say I was more than pleasantly surprised at its feel and playability; so much so that I brought the racquet back home with me to use more b/c I liked the feel so much. ~50 hrs. of court time later and it's still going strong . For the price, this is a great all around synthetic. Highly recommended if you're looking for a no-nonsense string. This is a great playing string and a tremendous value at this price.

Was having trouble keeping strings in racquet. A friend put me on to these about five years ago. He too, played with a wide body racquet, and the durability of these are great. I have since changed racquets (about one year ago), no longer a wide body, and use these in the new one. Love the feel these strings give for drops, spins, overheads, just all shots. The durability is the best for me.

One of the Best Control Strings

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