Reservoir tank will leak if not completely empty. Leaks at closed latch. Tank will not empty during normal flossing. Tank is very difficult to remove to empty each use. As messy to use as a Neti pot.
As the title says, this WaterPik does what it is supposed to do just fine, but it's big and awkward to use, and the run-off tends to go all over. If I had to buy again, I'd go with the traditional model with separate water tank.
WOW! My dentist recommended that I buy this and I could not be happier. I have been having my teeth cleaned professionally every three months and with this I can cut down to twice a year. After brushing, I cannot believe how many food particles I still see in the sink. I think this is easier than flossing. I have already recommended this to a friend of mine.
