Don't buy this product
I bought 2 of these packages so I'd have a stock on hand for the family & now after a few months I cannot return them. But that is not the reason for the bad review. The product does not work! The brushes do not turn as the OEM does, they only vibrate. I placed a piece of floss in the brush head and it never turned as you would expect.  I puled out a couple of brushes to see if only one was defective and they are all bad. I'm rather surprised that Amazon even allows this retailer to sell this product.
