Does what it’s supposed to. I cut a 29” tile, cut came out straight and clean. No chipping. For the lady that said it chips the corner every time, you should only make ONE pass and only use moderate pressure. In your video it shows you making several passes, especially on the ends and sounded like you were applying some good pressure to it. Make ONE pass, you’re only supposed to score it, then snap it. If you’re not familiar with the use of a tool, I’d advise you to watch some Utube videos before attempting. I’m redoing my bathroom and this is my first time tiling and using this tool and I had no issues with it
