Hand Therapy and Exercise Ball with an e-Book. 2 Pack - One Solid Color and One Marblized. Ideal for Stress Relief - Hand and Wrist Exercise for ADD/ADHD - for All Ages (Assorted Colors)

You can get a really firm grip and/or twist with this stress reliever without being scared that it will fall apart and spray some unknown substance all over. Just watch out because the cover can peel.

I have been using Isoflex exercise balls for years. Tried several other brands but Isoflex is the best. When you start with a new ball it will feel a bit stiff, but keep at it. The ball will soften and will conform to your hand. I use one in my home gym in between sets, and one in my truck at a stop light and one in my media room to use during a movie. This way I always get some grip reps in every day. I am 75 and still have a very strong grip and very strong forearms. This is due to dumb bell curls and the Isoflex.

These are for gifts. My employees love them. They can strengthen your hands or grip or help to relieve stress. They last much longer than the typical stress ball but can melt in the heat. They are the perfect size.

The texture/feel of the ball is great- the filling feels more like a sand rather than a foam, which is what I wanted.and couldn't seem to find anywhere else. I use this while I'm in zoom meetings all day, and it's amazing. However, I'm on my FOURTH one in less than a year due to the outside layer shredding off. While I do use this almost daily, I'm not especially rough on it-- just normal gripping and squishing here and there throughout the day. So it seems ridiculous to me that it doesn't last through normal use. It should be priced significantly less for this reason, or they need an engineer to take a look at that outer material to see how it can be improved.

This is the second time I get this Isoflex Therapy and Exercise balls. The previous ones I had lasted me around 2 or 3 years. These exercise balls feel very good when I squeeze them with my hand, and this at the same time helps me to reduce the pain in the moments when my hand hurts due to my osteoarthritis.

I really like the feel of these hand therapy balls. Only concern is the external latex rips and fall apart. I have ordered two sets of two balls, and 2/4 have torn the latex in the first few months of use. Maybe I am squeezing to hard, but would hope they would have a bit more durability on the external latex cover.That said, I have tried 3 other types of balls, and these do work the best.

They have a good balance of firmness and flexibility for my arthritic hands! Do recommend.

favorite stress ball out of all of them. Fine sand wrapped in balloons feeling which is a very unique and enjoyable experience
