Fitness Mad Men's Strong Grip Hand Exerciser - Adjustable Resistance Hand Strengthener for Grip Training, Physical Therapy & Rehabilitation - Perfect for Athletes, Musicians & Office Workers

Surprisingly good hand exerciser. I have bought several hand exercisers in the past this is for me the best one I have found so far. As it is made from rubber the harder you squeeze the more resistance you get from it which makes it very useful. As your hands strengthen and you can squeeze harder the hand exerciser provides more resistance which is excellent. Also by squeezing it between your fingers and thumb it strengthens your thumb improving your pinch grip which other hand exercisers just cant address.I found it to be far superior to the "spring loaded" hand exercisers with handles as it is smaller cheaper more comfortable and gives much better results across all fingers of the hand. The egg shape fits very nicely into your hand and it really does develop your grip. It can go anywhere with you and is very convenient.I purchased this for my friend as a stress ball. I was slightly worried about ordering it, as I wasn't sure what the material would be like or if it would even be suitable for my intended use, however, I had no reason to worry. The medium grip egg is perfectly fine for a stress ball and wrist exerciser - it feels very sturdy and my friend has been using it since April 2016 and it's still in very good condition. However, if dropped, the egg does pick up a lot of sticky residue from the ground, and upon taking it out of the package it also feels quite sticky, but this goes away after a while and it doesn't affect the use of it at all. I found the price to be very fair, and therefore I would order it again.I was diagnosed with ADHD a while ago and this was the perfect gift to myself. During lectures, rather than distracting others or losing focus, I'd simply do grip exercises or play catch with myself. It sounds sad, but now I'm pretty sure I could break bones with my handshake! The egg itself fits into my small hands perfectly and doesn't hurt my wallet either. From personal usage and abuse I'm certain of it's longetivity. The only thing I'd change is the colour - although it's good at hiding dirt.Hope this helps - five stars * * * * *Originally all I wanted was a stress ball to keep my idle hands from becoming destructive or overly demonstrative in the office while listening to nitwits blither on. And on. And on... I'd perfected patience in every other sense but my hands still gave me away every time! Anyway, I found this power egg thingy which not only fulfils the stress ball function I was looking for, but it's also firm enough to make it feel like I'm doing my hands good. In fact, that strange pain I'd been ignoring in the root of my thumb has lessened with the use of this item. And if things get REALLY bad, its firm enough to have some real effect when its thrown at someone!Update: Had to buy another one because my hubby "borrowed" mine. Made him keep the medium strength one though, kept the firmest one form myself!I bought this for physio after an operation on my hand and it is just what I needed
