I got the water flosser 3 weeks ago and it works great in terms of oral care.

I got the water flosser 3 weeks ago and it works great in terms of oral care. However, within 3 weeks the on/off button is sticky and it sometimes turns on properly but most often than not I have to keep pressing. Same with turning it off. Also randomly turns on after I have used and turned it off. Would love some help to fix this.

It’s very powerful. I feel my whole mouth is really clean afterwards in between teeth and bridges! I do not care for the rotation of the tip. It moves if you bump it up against a tooth, it can go sideways. Other than that, I love it.

This is a replacement for a dental irrigation system that finally died after about 10 years. I like the new one mostly. It is powerful and certainly cleans my teeth well.

This is a replacement for a dental irrigation system that finally died after about 10 years. I like the new one mostly. It is powerful and certainly cleans my teeth well. It charges quickly and remains charged for several uses. My only quibble is the shape of the water reservoir. The narrow part is hard to clean and I’m worried it might get mold in it after repeated use.

I really like the product. I placed Isopropol alcohol in the reservoir to sterilize it, but the alcohol destroyed the water reservoir. I wanted to purchase just the reservoir, but was not available. I was required to buy a new unit.

I was hesitant to use one but after using this water flosser it is a game changer. Definitely helps people with caps and crowns.

charge little extra and include a storage bag would be a plus, not only will keep far better looking, but also be great for travel or keep parts in one place.

only thing with this one is the tank (bigger)

My first/only water pic, so this is just a review of water pics in general.

My first/only water pic, so this is just a review of water pics in general. It does help with cleaning under my new bridge, but, as seen in the "how to" video, you will end up with water all over the place unless you use it in the shower. "Portable" is a relative term.
