This thing is pretty great. It's obviously not for everything, but for other things, it's perfect. Case in point, I had to remove quite a bit of 1" vinyl lettering and replace with new today. I tried getting it off with a fingernail first and it would remove somewhat easily, but every piece was leaving adhesive and breaking. Got the heat gun after it and made short work of it. No more residue and pretty much every letter would come off quickly and in one piece. I went through two of the smaller 2.0ah batteries which isn't bad at all considering how long it was on for.
