It's a clever design with the magnet holding it to the arm from the vise. The metal disc is attached with a sticky pad to the waste bin, but doesn't stick well. I ended up attaching the metal disc with super glue. Now it works. I find small clippings fall through the holes onto the desk below, so I might need to retro fit that too. I like the slim design and it's easy to take on and off to empty. Good practical design, that Stonfo seem to do quite well.
