Works ok but not great. Water tank runs empty too quickly.
No, I would not recommend this to a friend.

This model is designed small as it is intended for those that travel and have little to no counter space. Some users may find it necessary to refill the reservoir. If you prefer not to, a counter top model would be a better fit.
It really helps get food particles out from between teeth and helps keep stains from forming on teeth. I use it every night after brushing. It is very easy to keep it clean by popping the water reservoir in the dishwasher once a week.
