There's a cheap DUPE out there! Don't get me wrong, this brush is made well & works fairly well with concealer but it is overpriced and there is a much cheaper version available that works just as well if not better. This costs 24USD whereas the Everyday Minerals Eye Kabuki costs 8USD. I have even attached two photos to this review so you can compare how it looks. The EM eye kabuki is slightly fluffier but otherwise, works & feels remarkably similar. I can't believe nobody else pointed this out so everyone could've saved a significant amount of money.
I bought this brush at Sephora because I have horribly dark undereye circles with a lot of dryness & concealer just always looks terrible & cakey. This brush buffed it in nicely but it's not a miracle device for dry undereyes. Mine still looked cakey, just a little less so. The moral of the story is that the brush is well made, soft, and works okay, but it is not worth the price considering that there is an inexpensive dupe out there.
EDIT: I've also heard there's a Real Techniques dupe out there too but I don't own it (deluxe crease brush). It would be helpful to see the closeup comparisons.
