Review: Great product! - This is a game changer! My dental hygienist recommended a water flosser. I'd only known of the large tank ones. This is portable, holds just the right amount of water for a single flossing, rechargeable, easy to use, effective, and leaves my teeth with that dental clean feeling! I actually look forward to flossing! And I bought 3 as gifts!
Review: Love it - Have waited a while before positing my review so I can give an honest review. I am so happy with the water flosser. Not only is it affordable it works great for me. It comes with several different pick tips to choose from and you can adjust the setting speed which is key if you need them for implants like me. I had dental implants surgery about 6 months ago and use this at least 2xs a day. The charge stays for a long time, and you have to refill the water tank often depending on how much water you use at a time however that is a good thing because you really don't want water siting in something too long. Fresh water is always better. It is easy to change the picks and refill. Charging is fast and it even comes in a few colors. I got green to match my countertops in my bathroom! Highly recommend!

### ⭐⭐⭐⭐ Good for the price.
*by M***T on November 11, 2025*

OK, it works. I have braces. I bought this to help keep my teeth clean between cleanings and reduce unwanted plaque. It takes some getting used to, in that the instructions state the best angle for the jet is 90 degrees to the gap between your teeth. You can do that, but you have to practice. Otherwise, the battery life is good, the additional water attachments are helpful, and it's very portable. Having the ability to pack this in a bag is a huge advantage over a more traditional water pick type devise. Good for the price.
