Good design and size. Not too small. I like how it comes together although the tube doesn't lock down--it just clicks into place. Just a small amount of jostling inside your Dopp kit will slide the tube down and expose the bristles. It would be nice if the sleeve threaded into place.
The price is inexpensive so you won't be too sad if you accidentally leave it in the hotel bathroom.
The only thing I don't like about the brush is that it has a boar knot. It's a good boar knot for sure. Mine broke in and softened up quickly. It lathers well and feels good on the skin. So, as far as boar knots go, it's pretty good.
But it takes forever to dry. And you don't want to keep a wet boar brush wrapped up in your bag for a long time. I wish it had a nice synthetic knot that didn't take so long to dry. If I use it on the road I have to make sure to pull it out of the kit and dry it out when I get home.
