Shiny teeth, healthy gums 😁

This is a great water flosser! It has 6 water pressure settings and are quite powerful. Also settings for cleaning, orthodontist, sensitive gums and jet spray. It comes with 4 different water attachments. Compact enough for travel. It is much more effective at cleaning teeth than my previous one. The water reservoir is large enough so I do t have to stop and refill it to clean my teeth the way I like. A great water flosser without the price of expensive water flossers! Read more

Affordable and effective

Thick water pick is powerful, light and easy to use. The battery lasts a long time. I like it so much better than the expensive version I had before. I like that it comes with different attachments too. You won’t be sorry! Read more

Perfect for what I need! Cost friendly!

I am new to water flossers, and at my recent cleaning, my hygienist recommended trying one out. This was cost friendly and works great! It’s rechargeable, which is convenient. When you’re done, you can pull it apart and store everything together. It is definitely louder on higher settings. I started with the levels 1-2, and am now able to use the level 5 (maxes out at 6).

Great cleaning product. Price is awesome awesome.

It works great. It's my first one. I enjoy the different settings and how well it cleans my mouth.i like the design and fact that I can charge it. It's light weight. I just need to get more familiar with it so I stop shooting my face with it. Lol. Great product. Read more

It’s what the dentist ordered!

This is a great product. There are multiple settings for water flow and pressure adjustment. Perfect for the price. I use it daily and, of course, as needed. I have a dental bridge that’s was difficult to clean between that and the gums. This makes it a breeze and so much easier than flossing. The battery recharges quickly and lasts quite a while. I definitely recommend this flosser. It’s great for the price. Read more

Works great with braces

I bought this for my braces because my teeth never fully feel clean. I have loved it and it is very powerful and easy to use and it makes my teeth feel very clean. It is pretty tall but I feel like it’s a good size. Read more
