I went - I got an amazing deal on some Illamasqua, and it was good to be able to try out crown brushes in person before purchasing - some are fantastic, others not so much!
The inglot stall was packed, the staff were rude, and they inflated the prices! not impressed by them at all.
I don't think I'd rush to go again, it wasn't as good as what I read about the US IMATS.
