I was the 'beta test site' for their kit when it was first offered to the public.

Yes, I use it :) Good stuff! Big thing to keep in mind is to get a decent corded drill that does 2500 RPM. I had to buy the kit and the drill, so it wasn't cheap. Wasn't super expensive either, I think the drill I bought was $50-60, before I only had a cordless.

You won't get the best results without the corded drill.
