It's a huge regret for me to buy this brush. I seriously thought that the bristles would be soft and thus easy to blend. Unexpectedly, it performed like a super cheap makeup brush that if you had got a chance to try before buying, you would have never bought it. In fact, the bristles are like they're made by nylon or something similar. With almost similar price to Urban Decay ($2 cheaper in Australia), I do suggest that you guys should go for Urban Decay! Even their double-ended brush for eye shadow can totally work as a concealer brush.
Wanted to return but I wouldn't have known this if I hadn't tried!
