Query: Totally disappointed

I wish I could tell you this edger has solved all of my painting woes. Unfortunately, this product didn't work at all for me. I liked the idea of having a roller to do the edges instead of my normal paint brush. The roller always gets the paint on a little more evenly. however, the metal edge on this product left black marks against the ceiling, and the trim. It was like it was scraping off the paint beneath it. Also, the side of the guard with the black plastic also left marks on my ceiling. I would stick to the Shure-line regular trimmer, and use the one with the threaded handle for the ceiling.
