Has anyone tried the StewMac Fret Erasers?

Seems as if they work like soft little Japanese water stones.

Thumbs sure get sore using Micro Mesh for polishing frets. I have left the job to a Dremel tool with a polish pad. I put rubbing compound made for cleaning car finish on the frets first. Then I let the machine go on low speed, and the frets get a mirror shine in five minutes.
