Customers are saying

Customers frequently mention the Ultra Water Flosser's ease of use, its effectiveness in cleaning teeth, and its affordable price. Many customers appreciate the variety of attachments that come with the flosser, as well as its powerful water pressure. However, some customers find the flosser to be noisy and messy, and a few have experienced durability issues and water leakage.

    Not quite sure what all the fuss is about

    I gave this 4 stars because the machine works just fine, it seems to do what it's supposed to do, and I think it's easier than flossing. In fact, I think I might be getting more tiny food particles out than I would with flossing, because it's also getting stuff from along the gumline that *isn't* between my teeth, which is the only place the floss goes. So it's definitely more than just a 3, but until I hear my dentist rave over how much healthier my gums are than before, I'm not prepared to give it a 5. It's good, but it's not over the top. I haven't had any of the problems that some other ppl report, with leaking from different parts of the machine that shouldn't be. On the other hand, I've only had it for about a month. We only bought it because the dentist kept recommending it (and I mean she was *persistent*) for cleaning under my husband's bridges. So if she raves at my next cleaning, or if I start having problems in the meantime, I'll update my review, but for now, I go with a 4.

    Very easy to use and works great. I was surprised that the crevices between my teeth actually appear clean to the naked eye. I didn't expect it to work as well as it did. Hope it ends up holding well over time!

    it’s portable, powerful enough for me and the wife not to mention backed by solid clinical results. It's useful daily, and i could see it being usable in small bathroom setups. Solid pressure, no amount of gunk it cant blast! 10/10

    This little thing is powerful. I don't know if it's as effective as traditional flossing, but it's better than doing nothing which is what I was doing before. It's a bit bulky and the cord is not long enough which is why I knocked off a star.

    I love this, I noticed there was mied reviews online, but I got it anyway because it was a deal of the day. You MUST remember to press the grey handset before turning on the machine or else there is water all over the place. The cleaning is EXCELLENT!! I HATE flossing and this gets out stuff you never knew was there and now I floss daily.

    I absolutely adore my water flosser! It effectively removes a significant portion of plaque from my teeth and cleans bleeding gums. My dentist strongly recommends using it after brushing and flossing.

    good quality but noisy especially on high pressure. You have control of the pressure unlike many models that starts with 30 PSI this one starts from 10PSI, if you have sensitive gum; you are covered :)

    Came recommended by our dentist. We love it. Easy to use. Cleans very well even after flossing. Leaves the gums feeling clean. Gentle too with different settings. Highly recommended.

    So far this is a great product (owned 2 months at time of review), specially for the price. Has good water pressure, several different tips and a pause button. For the price, this is probably the best out there. Only cons - it is a little loud and the water tank could be a little larger. However, these are NOT deal breakers.

    First waterpik

    Dentist recommended Waterpik to remove trapped food particles in a tricky molar area and for gum stimulation. Was surprised at what it is able to remove compared to flossing alone. Noticed improved gum health after about a week or so of daily use. A little on the noisy side and messy at first but does the job.

    This is my second one — the first lasted 4 years before it died. This one works well and seems quieter than the previous one.

    With multiple attachments that can clean any grill, this product is a must have. Braces, pockets, tight teeth, sensitive gums, this one handles it all. Multiple pressures help avoid pain and injury.
