Review on Keenso Reinforced Inflation Replacement Electric by Gotdat Burton

I bought this for the mTen3 electric unicycle. Great fit. In the photo the valve stem looks like it is working. In fact, the valve stem is rotated 90 degrees, it is directed along the cross section of the pipe and not tangentially along the circumference of the pipe. I installed it anyway, it rides but there is no gap to put a cap on the valve stem to keep dirt out (I think I'll wash before venting) and there is a risk of marks on the valve stem caught . I've had less than 100 miles on the mTen3, I think I'll be changing a lot of tubes so I'll be more careful with my order next time.
