I have never used one of these products before until the other day I do highly recommend it my mouth and gums and teeth felt so nice and clean very easy to use do recommend it a little messy considering you have to hold over the sink but it does work great
I wanted one for xmas the tank runs out of water before I am done, and you can't control the pressure
No, I would not recommend this to a friend.

Thank you for your comments! Our Countertop models feature a larger reservoir capacity and offer a greater variation of pressure settings. The following link provides further comparison of Cordless vs. Countertop models: https://www.waterpik.com/oral-health/blog/countertop-cordless-best-waterpik/
