Hey, does anyone here use an induction heating tool instead of a torch to heat stubborn bolts and nuts? If so, what brand do you use?

I'm thinking about one because they are safer to work with around flammable liquids.

Example: Mini Ductor II

 

I retired out of a Napa and we sell one of those.
I want to say that somebody actually bought one, despite the hefty price tag for ours (which IIRC was about the same as the one at the link), and loved it so.....
