Hand Grip Strengthener, Rechargeable Digital Grip Strength Trainer up 220.4 Lbs(100kg) Hand Grip Exerciser Equipment for Strength Training-Forearm-Gripper-Finger, Stress Balls for Adults/Kids

At home on my desk, pick up and exercise my right wrist. Fits in the palm good and is comfortable and just the right size. I bowl and play golf. Had wrist surgery 2013 - successful, but still weaker than my left. Have to keep doing some kind of strength training. This was a great find, and really like the bright yellow color. I highly recommend this product and vendor - quickly received, and at a fair price.

I appreciate this product, it's small enough to stow away and judge grip strength before and after using other tools. I like that the charging port comes with a cap to keep it protected from drops or moisture.

If I place my index, middle and ring fingers flat on the three grooves on the ball, I’ll get a reading that seems skewed to the low side as I squeeze. I say this because, if I were to place the tips of those fingers on the grooves and squeeze, I get another, significantly higher reading (even though I can’t squeeze as hard using my fingertips).Also , however hard I squeeze this ball, the reading is substantially lower than what I get on my Camry dynamometer. I trust the latter more than the Diotuss ball because I have verified various users’ grip strength using the Camry.Therefore my sense is that the Diotuss product is useful mainly to track progress on grip strength, on a relative basis (as long as one is careful to use consistent finger placement), and should not be relied on for measuring grip strength per se. The other mildly positive aspect of the product is that, being a round shape, it is slightly more comfortable to use than the dynamometer. That said, the ball seems small relative to men’s size L or XL hands; fingertips on such hands tend to reach and partially obstruct the little screen that shows the amount of pressure being exerted on the ball.3/6/24 update: after the above review was posted, the seller reached out to me and offered to issue a full refund or send me another, upgraded grip ball of theirs. I actually declined their offer because, as I wrote above, the grip ball I have is still useful for training and tracking progress on my grip strength. I should also add that, given its small size, and the feedback on the pressure exerted, it does lend itself to being used several times a day. While it would have been nice to get a precise measurement of grip strength each time this ball is used, the most important thing for me is that it gets used. Moreover, I have always maintained that you buy customer service together with a product, and in this case the seller has demonstrated an earnest desire to make customers of their products happy. Therefore I am adding a star to my review (despite not receiving any financial or material benefit from this follow-up review).

I got this for a family member who does bouldering (rock climbing) as a gift. She has several other hand strengthening products, but this was the only one shows the strength of your grip. Of course as soon as it was opened, everyone had to try it, and try to beat her in grip strength (no one did.) It was a fun and different gift to give.

I originally wrote a negative review because the grip exerciser football had a defect. They contacted me, apologized, and asked how they could make me happy. True to their word, they did just that. No hassle, no fuss, no extra cost. Production mishaps can happen. I love a company like this that wants to make their customer happy.

Great for hand soap in the bathroom. Nice phone stand for easy entertainment while doing makeup or skin care. The sponge can so act as a moisture/drip catcher from the hand soap and also for cleaning. It’s pretty convenient but a little bulky.

It’s not accurate. Waste of money.

My son and grandson loved this! They kept trying to score higher than each other . Was pretty accurate and serves its purpose
