I love my Paintmate! As with any new tool, one should take the time to read directions and learn how to use the tool properly. I've used mine several times and each time the job went smoothly and quickly with NO MESS! Clean up is the same as any other device. And you've got to pick the right paint and prepare the surface properly beforehand. Sometimes you simply must use a primer to hide the old color. Then, you'll get much better results.
