DIOTUSS Grip Strength Trainer Tester, Hand Grip Strengthener Dynamometer, Forearm Finger Strengthener, Stress Balls for Adults/Kids, Rechargeable Digital Grip Strength Tester (220.4Lbs/100kg)

Good to easily know your grip strength.

I felt it was to hard to get a consistent measurement out of it. More of a gimmicky toy in my opinion.

Had this for approximately 6 months and bought to test and exercise grip strength. First the good: It charges, feels good in the hand and works very well as a stress ball or to exercise your grip. Where it fails is in the accuracy of the measurement. Basically it's not accurate at all compared to other grip strength testers and feels inconsistent. I've tied others and it's always way off. Decent value for what it is but if you need to know where your grip strength is at this probably isn't the thing for you and more of a novelty.

good to know grip strength a little small to big hands

UPDATE: While the original footballs we ordered didn’t work, their customer support team reached out and shipped (2) replacement footballs that were a newer version, and these both worked great. Thank you for correcting the situation! **** Bought this to put in my son’s stocking. It didn’t work, and because I bought it for a stocking, didn’t realize until Christmas morning and the return window is now past. Don’t waste your money.
