## Customer Reviews

### ⭐⭐⭐⭐⭐ Does the trick
*by M***F on 24 December 2023*

I've been looking for a convenient form of exercise for grip and wrist strength which is happily answered by this ball.My underlying purpose was to help improve my shots in badminton which relies on both, and after a few weeks of use 4-5x a week for about 10-20min a day Ive noticed some improvement already.Pros:- Easy to start with the automated system once you get the hang of the technique (instructional video link helpfully included)- This ball offers up a good amount of resistance and will likely offer something for all levels of strength.- Convenient to take with you out and about at the office or elsewhereCons:- Can be a bit difficult and uncomfortable to hold onto at first- I found this got a bit easier with more use and grip strengthening, however it would be nice if the grip was a little softer to hold.- The whirring noise. Doesn't personally bother me during use, but found it got annoying for others in the same room.Overall- 4.5/5Does exactly what I bought it for in a very convenient to use and store form. Quality build and feel; well worth the money spent.

### ⭐⭐⭐⭐⭐ Great for warmups after injury!
*by R***D on 13 December 2021*

I injured my wrist tendons 6 months ago rock climbing and had to take several months off to fully recover. As part of my recovery I looked into all sorts of aids and tools to help. I have previously had a powerball that I used as a desk toy and remembered that it was supposedly good for circulation and warming up tendons before doing something intense like climbing. I’m delighted to report that it seems to really help. I currently use the powerball as a pre-warmup to promote circulation to my forearms, wrists and hands. I also use it once I return from the gym at lower revolutions to cool down. I’m not a doctor and don’t offer any of this as medical advice but for me it works well and let’s be honest it’s a lot of fun too!

### ⭐⭐⭐⭐ Wears out fairly quickly but is an effective exercise
*by J***H on 21 February 2024*

I've worn down the mechanism after just a few weeks due to overuse. It makes a fair amount of noise now. Having said that, it did a good job improving my grip and wrist strength.
