Review on Theresa Hay Replacement Replaces Pre Motor by Diane Hubert

They are not durable at all. I have had the original brushes for over 2 years with no problems. I've seen and thought about these. "Oh, I have to replace them." Big mistake, one fell to pieces on the first move across the room. The rest didn't last long. The brushes have either fallen out or are bent/deformed and cannot do their job. Keep the originals and don't buy fakes like these.
