This product is not a replacement for flossing I work in a dental office and patients buy it because they don't floss, it's good to use when u want it's hard for people with very tight teeth wouldn't recommend and also the pressure is kind of painful.

This product is not cheap! I have some tight areas with my teeth and food always seems to migrate there. My hubby got me this to help with my issue. Let me tell you, the reservoir for the water is tiny, although it say it's enough for 2uses. Well not for me! The so called blast of air and water is cold and not very powerful. It does get out a bit of food stuck between teeth but, only after "blasting" it 3-4 times!
It sits in the cupboard.
I'll just keep using my waterpik which, is awesome by the way
