I've only had this for two weeks but it gets into the trickiest spots and makes sanding metal easier. I noticed that it has a cover at the base where you install the new strap. I was wondering if I need a torx or something to unscrew it first to gain access to tighten the new belt. It's not like this. It features a handle that can be easily rotated by hand to open or close the protective cover. You will not be disappointed with this tool.
