Comments: This string came stock on the Gearbox 1.0 170Q racquet I just bought. During my 2nd or 3rd game I had one mis-hit (to me, a mis-hit is anything outside the sweet spot) and the string broke. I am a hard hitter and most of my breaks have come from off-center shots. If you're known to be a ball-crusher, then you may want to invest in something more durable.

Comments: 18g GB Mono is my favorite string. Just stiff enough for extreme control on all shots. Hard shots and drive serves go where I want. Lob serve placement is very very consistent. Really shines on touch shots. Easy to find the length of the court as well. I thought mono would be too harsh, but I was wrong. In all, I find that I'm much more consistent with these than any other strings I've tried and I attribute that to having a string bed that behaves the same no matter when, where and how I strike the ball. Thanks GB!!

Comments: I've been using this string for a while now. Plays great and has great durability. I have several hard hitting open level players that I string for and haven't had much trouble with breakage. Great string for the money.

Comments: Amazing control and powerful...yet soft feel. HUGE upgrade from factory Premium Mono. Have not felt this good of a string since Technifibre's best HPR 505.
