The Champion Automatic Penis Pump for Men

Not very good instructions about how long to keep it on

On Time

Package came on time. It’s great, start small to get comfortable with it. It does the work for you 25mins a day.

Does what it says...but

This device performs well, and does everything its seller claims it will do. Only fault I find is that it lacks a feature that I think would be beneficial for the user. It's pre-programmed to range from a low negative pressure to a higher negative pressure and then immediately drop slowly to the original pressure, and then go back up, etc. You cannot make the pressure hold at any given point. Maybe there's a good reason for that, but I don't know one. The company was good to deal with. Responded to my queries immediately.
