I don't have the knock-off valve, but I do have a couple of the airpower valves. And they are UNbelievable. I will not put together another jet without one of these valves. They take up much less room, work perfectly every time, and the anti-lock brake function is nice for keeping your tires from wearing down. Not to mention the built in pressure gauges and gear-safe functions on the pro valve.

Contact Todd and get the original valve.
