Sorry to hear that. Hope it gets settled out or you get used to the brush.Received my 31mm brush today. Love everything about it except for the fact that the knot is a bit lopsided. I've had a Zenith in the past which was terribly lopsided. I wish Zenith was better with setting their knots.
I'm very OCD so this really bothers me. I'm going to use it for a few more days and let more hairs split, but if it still looks lopsided, I'll have to contact Stirling.
The other Zenith I had never recovered even after fully breaking it in. I don't expect this one to straighten out either.
