Allan Ambrochowicz: I've been using the balls for a month now, and the range of motion in my finger (damaged by a table saw accident last summer) has increased tremendously. I'm sure other rehab devices would work just as well, but for the price, I couldn't be happier with the results.

CJ: These were nice. I got them for giving Platlets at the Red Cross. Flexable for light fast squeezes. Much better than the foam balls. These fit in your palm and are strong enough to get some exercise while donating. The only draw back is the color. The yellow has gotten dirty looking in my go bag.

Jasmine: I like these so much better than the more common stress balls that you usually see. These are a more dense material and feel like they'll last a lot longer. They have the feel of a rubber bouncy ball with a grip to it, so if you're gripping them in your hand, they stay in place. So if you prefer to throw things when you're mad, use caution when holding these because if you're stressed and throw one of these, it could do some damage!

Piano Prof: The shape of these hand grip eggs is perfect for the palm of my hand. They aren’t too big or too small and their density gives me enough resistance to get the best result. Keeping them by my computer is a perfect place to de-stress as I work. I like the fact I can gradually increase my resistance as I use them. Interestingly, I have found they work wonders on my feet as I roll my foot over them and push down on them on the ball of my foot. I wasn’t planning on this, but found the stress in my feet was relieved as well. They are perfect to take with me when I travel for work. Enjoy!
