If you want an automatic shut off, look for one on Amazon. I purchased one from Belkin an Outlet Timer. It has a button on the side so you can set it to turn off in 1/2 hour, 3 hours or 6 hours. It has saved my butt a few times with my mini iron that I used for paper piecing. I ended up putting my surge protector on it that has my sewing machine, Ott lights, etc on it. That way I knew everything would be turned off in xx time.
