I think I use this brush more than any of the others I have - which isn't a lot, honestly. It's great for packing a lot of eyeshadow on and it's the perfect size for my small lids. I think it was only a few dollars too, so that beats out buying a MAC brush any day.
One of my all time favorite brushes! This brush may be small, but it packs alot of power. It's reliable and I've been using it for over 2 years now. :) If you're looking to invest some $$$ on brushes ( & don't want to go the MAC route) these brushes are an AMAZING alternative. (:
