My first pump purchase was a real disappointment, so when I bought a new one, I wanted to make sure it was going to satisfy me. I ended up buying an automatic rechargeable vacuum pump that you just insert and push the button for a five second pump. You can do that over and over as many times as you want and it works great. It seals my cock in nicely and I get an hour of continuous use before a recharge. Love how it feels and I'm astounded at how much girth it adds. I've written a blog about it.
