Review (3/5): Generic brush vs OEM replacement brush
well, these replacement brushes cost 10% of what the OEM brushes cost. They don't last as long as the original. The bristles are just a little softer than those of the original. Sometimes the fit of the brush onto the metal post is not perfect but that doesn't happen very often. The blue bristles are just dyed blue, and they never fade like those of the original where they indicate when the brush is worn out and needs to be replaced. So these are not perfect but they are darn good. And really, I have bought both kinds over the years and I have now come to the conclusion that the "generics" are just fine. Think about it. The originals last only about two times as long and they work pretty much the same. I just see no point in spending 10x for something that is barely 2x better.
