1 Rotadent Rota Dent Brush Head Flat Hollow Zila by RotaDent

Waiting for replacement of faulty brush head that I ordered on Nov 19.

I have been using/buying this brush head for years and have never had a problem however the last one I purchased lasted a couple of days and seized up. Overall I am happy with this product and will continue to buy it...just had a bad one this time.
