Poor- travel flosser never worked on our first trip.
Product for home use works fine.  However, the whole point of ordering this system was the travel flosser.  We took it on a trip and it ran for 5 -10 seconds and then would never charge.  Once we got home we tried charging it again and the travel unit still would not charge and we were not able to use it. Very disappointing.  travel flosser not quality product at all  UN USE-ABLE
