LIYUANBAIHUO 3 Pcs Tennis Training Balls with String, Tennis Trainer Replacement Tool, Ideal for Indoor and Outdoor Practice (Black)

My 9 year old bought it for tennis practice but it keeps on breaking. The quality of ball is also not good.

This is cheating. What is shown in the pictures is not delivered. I ordered after looking at the pictures where it shows that the string can be tied in the ball manually. But what I received is, the string is in-built attached to the ball and there is no threading hole in which I can re-tie the string if it is broken. This kind of ball-attached-string breaks within 70-80 shots and ball becomes useless after that.

Grandson (8th grade) likes them.

these were easy to tie on to the base I had. IT works well.

I bought these to replace the ball on a pole thing where the cord is inelastic. These are on elastic cords so we ended up with unexpected fun as the balls went every which way. But not what I had intended.

Very bad

my German Shepherd loves the balls with the string because he has hip display so he can’t walk so we try to find things for him to play with but the bad thing about it is you don’t make it tight enough so when they bite on it, it just falls apart. The string comes out. I don’t recommend it.
