MAC's New Pro Longwear Collection!

Went to MAC yesterday and saw all these beautiful lipsticks...  the girl who works there told me that it was a new lipstick that is suppose to stay on for up to 12 hours!! Wow, hard to believe...  and apparently it's a collection that's gonna stay on the counter for a long time. I really like the lavender color! She had on one of the neutral colors and it looked great on her. There's also a concealer and foundation.
Has anyone tried these out yet?  What is your opinion?
