I got this board and pump. The board has been good so far, but yes, I suspect the pump is really poor quality, and not as efficient as it could be. After doing some research, I'm thinking about trying a Red Titan. I don't mind pumping manually (if I can get it all the way up to 15 psi), but I'd like to just use one device, if possible.
