I found out about the induction heater from a shop foreman, who told me what a lifesaver it was. But since I work on my cars as a hobby and not professionally, I didn't know if I could justify the cost. Thankfully I took the plunge, because this thing is a lifesaver. It is fantastic for loosening frozen and corroded bolts. It's much easier to use than a torch, safer in many places, and much much faster. It only takes 3-4 seconds to heat a bolt up to the point where it comes out easily. The first time I used it was after I had already snapping a bolt. After heating it up with the induction heater, I was able to back it out of the threaded insert that it was frozen into like it was brand new hardware. Since then I heat up anything I'm taking out for the first time to be safe. If you've been considering it, don't put it off any longer!
