Sure beats a $400 unit!
Question:what did you use for a power supply? Battery or DC power supply?

Did you use the whole coil on that screw? On a nut, you can only get a couple loops around it, so I wonder if that device has the same amount of oomph as the commercial ones?

If it works, you have a great bargain tool, nice!
