Despite there being a quality issue with one of the carabiners, this is a great little kit and worth the money.
The Micro Traxion pulley takes all the prusik minding out of the equation. You just hook it up and go. The z-pulley system is so easy to set up and execute. This kit would really shave a lot of time off a rescue effort. There is no more need to tie prusiks or tend them during rescue.
The Tribloc micro ascender is a nice little piece of hardware. The only issue I could see with it is that it's so small you could probably drop it or lose it if you fumbled while in a crevasse. I think that I've read a recommendation for putting a tether on it. That might be a good idea.
