I own one brush...the omega boar 'Pro', the well known big one that I got with my starter kit and I've had it for almost 2 years now. I start to develop interest for brushes - although I'm very happy with my boar brush!- and also my brush has shed a few bristles over time and I'm wondering how long a brush like that one can last. I'm not looking at a good reason to buy a new brush, but one is never too careful to plan ahead, right?! Also, much to my shame, I have to say that I never bothered to take care of the brush, but I will do so promptly as I read a ton of threads talking about soaking the brush in vinegar etc...
