Hand Grip Strengthener Grip Strengthener Grip Strength Trainer teenage boy gifts The grip strength can be adjusted from （5-60）kg Perfect for Musicians Athletes and Hand Injury Recovery

Great grips quality made and very sturdy size are just right

Good

Decent enough value, they haven’t broken yet lol, I bought these to keep me a little more occupied whilst recovering from an operation, decent enough for building up hand / wrist & forearm strength, adjustable tensioner too

Brought for present for 11 yr oldFound them very stiff to start. Made a difference

Works great, does what it's meant to do. But the counter clicks quickly become very irritating!

Excellent

I think these are for adults as they are very hard to grip closed , I bought to strengthen a teenagers hands but to hard to close.

Does what it's meant to.
