As a sheet metal worker by profession, I had to try this out. This is a simple tool for bending sheetmetal up to 1mm thick (soft metal, like aluminium). Easy to use, but it's a little bit of trial and error to get the correct angle.
I'm giving it a full score, because it does what it's supposed to do, it's cheap, and is a valuable tool in my hobbyroom. I've already made a new transmission/skidplate for my scale crawler, see pics in link www.link
