Love this thing! Had to get the 12".
I wanted to smooth wall the old textured wall. It took a while to get it right, most the consistency of the mud plays a huge roll. Cannot be too thick, water it down, if it chatters, you need to add water so mist it before wiping w tool. I have gotten good in a short time and have decided to do most of the house. First coat of mud is thicker to fill the texture but after that, its pretty sloppy. I sponge sand the first coat, wipe down. Second lighter coat and hand sand, third coat (the mix is sloppy) is touch up, sand and i'm done. I love the new look! If you are having issues its usually the mud being too thick, takes almost as long to mud to right consistency as it does to put it on the wall and swipe down. Sometimes, if the spot doesnt look too good, i mist the wall, wait a bit, mist the tool and wipe down. Also remember that the first stage is the ugly stage, where you think, this is not going to work...lol
