I've used it and hit pan and really like it. I like the fact that it is pressed, it doesn't have a lot of ingredients and it works. As with most mineral powders the trick is to use a little and buff and buff and buff until your arm falls off and frankly I can get a better result in a less time with a good liquid foundation/TM but for the warmer months when my oilier skin goes into overdrive this works really well.
I think that there is some problems with shades though, so it maybe worth lurking around the HoF counters to have a try out. Hope that helps.
