Query: Take care of it, and it works exactly as advertised

My wife and I both love this thing. Just take care of it like the instructions suggest with regards to cleaning and lubing the seals, and the thing works perfectly. We bought one to see if it works well, but are about to buy a second so we can paint the whole house via divide and conquer.Don't let the duckbill seal get clogged with paint by letting it sit around too long during breaks without covering it with plastic. That's one of the things that makes it leak - one time. Now that I take care of it, it works perfectly. If we didn't have a lot of painting to do, I wouldn't bother, but since we do, this thing rocks. A huge time saver.
