After using this brush daily for several weeks, I'm very satisfied. I bought the "handy" size with mixed boar and synthetic bristles for my medium-length, medium-thick hair. It feels great on the scalp, and gives the hair a more smoothed-together look as well as some nice volume. The little brush for cleaning is useful. Overall, if you can afford the investment I think it's worth it. I was a bit worried by the Mason Pearson website statement that only authorized sellers can offer bona fide Mason Pearson brushes. Tressence acknowledges it's not an authorized seller so there's no way to know if they're selling the real thing, but the brush is beautiful, works great, and comes in a gorgeous old-fashioned box, at a reduced price. All good!
