All right. Order delivered as advertised and combined with seller. THE proposal is interesting, but not say if will be efficient. Because of retardation generated by an automatic system detection balance and gravity, can be error instant response device on curve.
I received the product very fast. I think it was less than two weeks which ia very impressive, considering that the post office was closed for 6 days because of Christmas. The product works perfectly. I didn't install it to the bike but I am sure I will be happy!
