Review on Brushes Replacement Compatible RV1001AE Accessory by Lorenzo Moulton

I've had these brushes for two days and in that time two of them broke. The bristles were pulled out of the first, and the second snapped where the flexible rubber meets the harder plastic. EDIT: A week later I reattached the last two brushes as all six of the previous brushes broke off as shown on the left brush. in the picture.
