Earlier I had posted that my Tweezerman shave brush had the bristles pop out of it after 3 weeks. Well I sent the broken brush back to them and they immediately sent me a brand new one. I did find out from some of you guys that I had not been properly caring for the brush and that probably caused the knot to pop. So I now have a brand new Tweezerman and if I end up poping the knot on this one I will take the advice I was given and epoxy it back in. I am pretty pleased with the service of the folks at Tweezerman, and for the price I think they make a pretty good brush. So if anyone was wondering whether or not Tweezerman would honor their lifetime guaranty, they do!
