CoreFlex 4D is the best product of its nature hands down. I will be 62 this Month on the 28th. So I've seen the early models of the wheel in the beginning stages. That put a lot of stress and pressure on your wrist area. The CoreFlex has been a game changer since day one....
And what's even better than the product is the customer service! I reached out with an issue of how can I fixed this and they made it right immediately with than a few days.
Thank you CoreFlex 4D for all yo do, I'm a customer for life😂💪🏾
