Serenilite Hand Therapy Exercise Stress Ball Bundle - Tri-Density Stress Balls & Grip Strengthening - Therapeutic Hand Mobility & Restoration

I can't say how durable they are because I have only been using them for a few days, but first impressions are good. They ate accurately graded as soft, medium and hard. They are well packaged and come in their own handy storage tube. I am.using them to strengthen the fingers in my left hand after an operation and, so far, they are perfect for my uses.

Really good quality. I have fractured both my thumbs. I can't use them to full capacity as yet as the resistance is too much and I'm using a foam ball. However, even at this stage I can feel the difference in the soft, medium and hard. These are really good for building up strength and grip, the fabric feel is better than plastic. They're the right size for my hand.

I suffer from arthritis in my hands. These exercise balls are great at bringing relief
