I remember reading on either B&B or TSD that a guy ordered 10 handles, and two arrived cracked. There were also issues with the inlays falling out.
In general though, almost all the posts I've read about Kimson are positive. A few years back I offered to go through every page of their website and send them corrected descriptions in proper English (plus all future products), rather than the pidgin English used on their site, in exchange for a brush handle. They turned me down. I think that was stupid of them, or at the very least, shortsighted of them, all things considered.
