So far so good! And we really appreciated the little hair cutting tool for the roller—nice touch. We've replaced one bag, one brush head, and one filter using this bargain kit so far, nothing much to complain about. It's not quite OEM quality but it's very likely going to work well enough. We expect to go through one kit like this per year. Be aware that the rotating brush head replacement (the small round head ones, not the big rollers), have a little philips head screw that you have to remove. This was kind of hard to get off at first. We haven't used one of the replacement rollers yet, expect that we'll go through about two a year with our C10 at the current rate of wear.
