GSiBounce Reaction Balls for Agility Reflex and Coordination Training (72 mm)

Strong, very durable and my daughter enjoys trying to catch it

As soon as you drop the ball, it never goes higher than 1 inch making it impossible to catch. It will go sideways as most training type bound much higher at an angle. I did notice the nobbies are much smaller that what I saw at the sporting goods store so I'll have to get one of those. It does work better bouncing high on a wall. Other than that, I won't recommend.

Develop better depth perception and just get better at responsiveness.

I returned it. The deviation is too big. It’s very heavy and may pose a risk of injury or it can damage your furniture badly if you play inside. You have to learn how to throw it correctly to work otherwise it will be rolling. We tried our best to adjust to it but ended up with a bruise on my leg. I understand that the ball is supposed to help you to develop reaction skills but we could not figure out how to make it work.

I found this product to be exactly what I was looking for. I use it to play cricket by myself. I throw it at a wall and play at it with a bat when it comes back at me. It bounces unpredictably, coming off at various heights and angles. It’s like facing some champion spin bowler on a turning pitch!

Great reaction tool for son who wants to be a goalie

I dropped these balls 10x from head height , and 10x from waist height- twice they bounced back with fair to hard deviation AND high enough for me to catch them. The other 18x they hit the ground and darted off in a sharp impossible direction less than 1/2 a foot from the ground. Not a good training device at all. Sent back.

Very happy with the quality of these reaction balls.Durable and nice color options.Strongly recommended for sports enthusiasts.

It’s a really great product brilliant bounce, brilliant varibality of bounce makes it great at testing reactions
