I have just one complaint and it's minor: I wish the bristles were slightly less stiff. The brush works very well, overall, but in harder to reach, tighter corners I've noticed that it leaves some of the cobweb and material behind since the bristles aren't more flexible and thus don't bend easily to capture them. This might not be an issue for others and as I noted, this is a minor complaint!
