I had a conflict ordering as the reviews seem to be split 50/50 on whether these parts fit properly. As for filters. OEM parts are perfect. I can't comment on their durability or if they are truly HEPA but I am happy with them. As for the side brushes. Many reviewers wanted a smaller screw to fit. I was willing to drill a hole, but it's not necessary. I acknowledge that the hole may be 1mm smaller than the original. Just tighten the screw to enlarge the hole before attaching to Roomba. Then append. No problem. Again, I can't say how long they will last, but they fit perfectly. I hope my review at least puts an end to reviews where side brushes are considered incompatible.
