Query: Sheds fibers causing damage - caveat emptor

Just two weeks after the 'returns window' closed this brush is shedding fibers that get churned up by the stylus and then disintegrate as dust into the grooves. I had an unbranded $10 brush like this before which did the same thing - I just thought it was because it was a cheap knock-off. I bought this one thinking that the $24 audioquest brand would be different- how wrong I was! It would be a great brush if it did not shed, but it does shed, so it's just so much trash.
