Looks like the brand name water flosser only without the brand name. It's amazing how many little specs of food this device can flush from between my teeth.

Looks like the brand name water flosser only without the brand name. It's amazing how many little specs of food this device can flush from between my teeth. I use it morning and night, only takes a couple of minutes, then brush as usual with my electric toothbrush. I was getting a lot of staining and buildup between dentist visits. This has cut that down dramatically. Caution: Keep your mouth closed until you hit the Off button if you don't want water all over the bathroom and you - lol.

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.

Glad to find replacements for the water flosser eventhough they are clear plastic and they fit.

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.
