inaepeak 396lbs / 180kg Grip Strength Trainer, Rechargeable Electronic Hand Dynamometer, Digital Grip Strength Tester with LCD Display, Adjustable Hand Grip Dynamometer Hand Exercisers for Strength

I bought this just for fun, to see what my hand strength actually is — and it does exactly what I hoped. It feels solid in the hand, easy to hold and use. The screen is clear, and the readings seem consistent every time. Setup was quick, and the built-in battery means no messing around with replacing batteries. The multi-user feature is a nice bonus. I’ve only used it myself so far, but it’s cool to know others can track their own scores too. No issues at all — works perfectly straight out of the box. Great value for what it does.

Works fine - I presume the load cell is accurate. Construction quality a bit naff, the grip adjuster is rubbish. Value acceptable overall.

For everyone saying this does not provide an accurate reading, it does. You just need to set the grip handle to the highest point towards the spring rather than having it all the way down. A typical grip strength required to close a captains of crush 3 gripper is between 80-85 and I can close it which checks out. Everyone else I’ve had try this dynamometer has had ratings that check out with their gripper status. If you want an accurate cheap product pull the trigger on this one.

The Inaepeak grip strength tester is sturdy, accurate, and easy to read. Perfect for tracking hand strength progress during training.

Packed up after returns date, (1 month). No hope of getting a refund as product from China I'd give it zero if I could beware

Works well although it's not the most comfortable thing to grip and squeeze hard. Had quite a bit of fun with this challenging some friends.

I find it simple to get a reading as it reverts to the highest grip strength you achieved as soon as you release your grip. I haven't attempted to assign users and keep a record on the tester itself - for my purposes pen and paper work fine. It's stiffer to squeeze than I thought it might be. As I'm still suffering the after effects of hand strain, I limit myself to a few squeezes every other day and the rest of the time I'll pick up a a small fairly spongy ball to exercise my hands. After just a week or two I'm getting slightly better results - going from 'normal' grip strength to the lower end of 'strong'. I'm not sure whether this really is an increase in grip strength or just an improvement in my technique, but it's reassuring after the damage that I did to my hand.

The handle is big enough, even for my humongous hands. Not sure what these other reviews are on about being too small. I can't say if it is accurate or not, but it is consistent. If you want to compare with someone, make sure you use the same device. The grip adjuster is useless since it causes the handle to bottom out. The one half of the handle deforms under pressure untill it touches the other part of the handle so you're not engaging the strain gauge. You're just pressing plastic against plastic. It can be hard to get a good grip on the slippy plastic but you'll get used to it. As long as you don't adjust the wheel thingy, it gets the job done to see if you're improving or how you stack up against your friends and family.
