Seems like an excellent purchase so far!
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.

Nice extras
This kit is great to keep my vacuum running! It’s nice to replace the brushed when they get tangled with pet hair.

buy from Eufy only for reliable fit.
vacuum bag doesn't fit correctly and the vacuum doesn't register it and won't work with it.
