Its works great, my heart meds make it tough getting things going once in a while, my wife sure is happy I have this, its a little wide but gets you rock hard and ready - fast - no leaking air problems and easy to clean.
Did alot of research on pumps before buying one. The biggest complaint against this pump was getting a factory defect one. Mine works great. I was going to get one of the bathmate hydro pumps but they are close too 100$. I just fill this one with hot water and use it in the bath. If you combine pumping for 20 mins every other day with testosterone supplement you can get some decent permanent gains
