Your roller cost 35 bucks for starters, it’s too much. The roller is not made to last. It’s designed so the dust gets trapped into it and stuck, and the ends glued there’s no way to pull the dust and fibre out without wrecking it. Then you sell it for almost quarter the price of the whole thing. If it wasn’t so badly made that you could actually last for a bit longer, say a couple of years… that would be ok. If I could just pop the ends off and pull out the dust that would be good. Then I wouldn’t mind buying a new one when it really wore out. $15 to $20 bucks wouldnt be so bad. But as it is, I gotta say it’s a bit of a rip.
