Review (5/5): The customer service was also, I might add, very friendly, helpful, and quick to respond!
I am actually pretty happy with this brush for the almost week I've been using it! The bristles are good and stiff, so they were able to get through most of the layers of my hair, and it does a seriously terrifying good job of volumizing. Or floofing, in my case. Easily remedied with a little spritzing with water. Or not, if you're into floof.
There are a few cons to the brush, but nothing that should stop you from buying it, should you be looking for a nice brush to give yourself a nice scalp massage/shine to your hair/add volume... and other such things. There IS a smell that comes from the rubber bedding that the bristles rest in from using recycled rubber. However, if you let the brush air out after unboxing, the wafting odor goes away. You'd literally have to stick your nose in the bristles to be able to smell the rubber scent again, and it doesn't brush the smell into your hair. Believe me, I've done just that, much to the angst and irritation of my poor snoot.
The bristles are juuuuust slightly shorter than I like, but it still grazes the scalp enough to give some nice stimulation (a pretty darn good itchin' relief) to your scalp. I know most people are used to a brush giving the full on scritchin' experience to your scalp, but I find that usually a lot of that, no matter how delicious it feels, usually makes my hair uber oily.
Other than those very little things, it's a good boars bristle brush to invest in, I think!
