I saw another thread where a someone emailed about this issue and got a free replacement.
I purchased one from the ebay seconds store and I'm having issues with bristles falling out. I've only had it for about an hour and just ran my fingers through and bristles were falling out. I tried pulling on some of the fibers just a tad (definitely not hard) and bristles were easily coming off.
The ebay description doesn't mention anything about bristles falling out. It just states that there may be knots in the handle. So I'm hoping they will replace it.
See the damage from just a couple of minutes of running my fingers through and pulling lightly at the fibers.
