Review on EVERYMILE Balance Board With Handle For Core Trainer, Exercise Stability & Physical Therapy Workouts - Wobble Balance Board Portable Gym Trainer by Michael Heidelberg

The surface is slippery if you have socks on. Fine for bare feet or shoes. The wooden wobble boards with sand-paper like grip on top have better gripping.The holes from the handles are annoying. You have to rotate it so that the holes don't line up with your feet.The rounded bottom makes a more dynamic feel than the wobble boards that just have a support in the middle. I like that, but for the other reasons I returned it.The seller had great customer service and in addition to accepting my return, they sent me different product that I enjoy. Can't complain.
