My dentist recommended that I get a water flosser since I’m not the best at remembering to floss 2 times a day! Like who does that anyway?? So I got this to try because I figured it was a better option. So far, I like it. My teeth feel clean after using it. It’s VERY easy to use and it comes with 4 replacement heads. I like that it is portable and can be used anywhere. For my first experience with this, i don’t have anything bad to say about this product other than don’t put ice cold water in the reservoir unless you want you don’t have any tooth sensitivity.
