Can't think of anything even slightly negative. Good website to help explain the process.
Blair, JT and Sterllng. Super nice, smart guys. All very friendly, knew their stuff, and were willing to answer a lot of questions from a large audience of interested observers.
We had to step out briefly before the guys had finished, but the place was spotless and tidy.
Worked through Rainbow International, so they made the decision to use True Level, but I believe having a local office helped.
