I got this set of replacement parts for my E5. It came in a simple plastic bag. The set includes 4 filters, 4 spin brushes, 2 rollers, a screwdriver and a cleaning brush. The rubber rollers appear to be nearly identical to the OEM except the end pieces are round instead of hexagonal. I love the little screwdriver and cleaning brush. Roomba should have included it with every vacuum considering how much money is spent on one. I tried using this set and so far so good. Feels like decent quality.
