They are a phenomenal product. Great technology, so well constructed. No sand, stress balls or any thing to fall out or lose. 30 seconds of doing it and you have a great burn. I would recommend this product to everybody

Such a simple concept and extremely effective.
Having a portable method to train grip and forearm strength is a game changer.
It’s perfect for a quick warmup at the gym, or before playing a racquet sport. I even pop it on my desk during long calls just to get a short burst of training in as needed.

So easy to use - I have had two surgeries in my left thumb and right thumb is also weak with arthritis. This is so easy to use - I have it by my chair and can use it anytime/anywhere !! Great grip strengthening exercise.
