I bought this two years ago and loved the convenience of the flosser and toothbrush in one unit. Both were fantastic! Loved the timer on the toothbrush and the different tips for the flosser. Almost two years to the date of purchase the toothbrush stopped working. I was hoping to be able to buy a replacement brush, and was disappointed this was not an option. Now I have a great flosser in an extra large unit since the toothbrush isn’t working. I really made an effort to keep the contact areas clean on the brush. This was a waste of time. I love electric toothbrushes, but have a limited number of outlets, there is not a spare one for a new toothbrush and my flosser, so I have to ditch the whole unit.
