Seriously. I can use it to desolder huge capacitors that might take me a minute or two (for one capacitor) in a few seconds. I also had one circuit board that had dozens of the exact same relay, and instead of having it be repetitive and boring, it was repetitive but very fast. I had all of them desoldered in only a few minutes.
