Is an Induction Heater for stuck bolts worth it?

In repairing/refreshing the rear suspension of this 2009 Dodge Journey, I decided to buy an induction heater to see if it lived up to the hype and was able to make removing stuck bolts easier. In short - it works!
I first completed the repairs on the passenger side without yet having an induction heater. After the difficulty I had removing some of the bolts, I decided to try one of those induction heaters that kept popping up in my feed. I does a good job of heating up the bolts to make them easier to remove. I went with a 1200W heater. This will come in handy for future repairs, as I live in the rust belt and am constantly battling corrosion and stuck bolts during my projects.
