These brushes hold up very well with continued daily use. I purchased them as there was only one brush in the original purchase. Both my husband and me use it and love the results for the health of our teeth.
Brush is too small and the power is lacking. Teeth don't feel clean after using.
No, I would not recommend this to a friend.

We are sorry to hear you are not completely satisfied with the product. The toothbrush head is designed to be small to fit in the back of your mouth at the correct angle for flossing. This does not make brushing any less effective.
