I bought this inflator because of all the hype about it being able to quickly inflate from 0 to 35psi etc and wanted to use it to pump up your rudder. After 15 minutes of plugging in, the board barely inflates (didn't even reach 0psi) and the unit shut down due to already overheating. Absolutely useless disappointment. Update: Not only is the pump itself useless, but I contacted their customer to see if there was anything wrong with the pump (as it should be under warranty) - after 3 emails I still haven't received a response. I will only return it to Revane for now.
