The Velocity Vibration Ball is small yet powerful. I use it for my stiff early morning hands, fingers & wrist, also really good on my feet. High speed is great.
I received this product as a birthday gift. i am a recent cancer survivor who developed neuropathy in my feet during chemo. This device makes my feet feel so good and I believe it is also helping with my circulation, too.
So far so good. Love the different levels and will definitely recommend to friends and family. Used on neck, back, legs, feet and glutes and is fantastic.
