I love this!
I've had several marks in my dark teal dining room for several months.  I was dreading dragging out the paint can to do touch-up.  I saw this advertised on TV and decided to try it.  It works great!  I filled the tube with the dining room paint, then touched up the marks in the dining room wall.  It worked exactly as advertised. I was able to touch up the dining room in a couple of minutes.  The tube is till full, so I can touch-up again, as needed, with very little effort. This is a great idea that was implemented perfectly!
