I love my Paint Buddy! This is a great touch up tool to have handy when you get nicks and scratches on your walls. All you have to do is fill up the Paint Buddy with some of the left over paint from your wall and it's ready to go anytime you need it. I have had my Paint Buddy for over two years and the paint is still as fresh as when I filled it. It has a replaceable mini roller on the top that I have found very easy to clean, but if it gets too dirty or you want to replace the color of paint in the handle, you can buy replacement rollers. There is a button on the side that you push down to keep the paint sealed and fresh in storage. When you are ready to use it, you just pull up the button, turn upside down and squeeze the handle and the paint transfers to the roller. My walls are textured paintable wallpaper and they get knicked very easily so this is a valuable too for me. I would highly recommend it.
