Dentist can tell I changed something.
I am absolutely loving this water flosser! It does a fantastic job of getting my teeth feeling dentist-clean, but the standout feature for me is definitely the massage mode. It feels great on my gums and has made my oral care routine much more enjoyable. The pressure is perfect, it’s easy to use, and it feels like a high-quality device. I highly recommend it to anyone looking for an effective and refreshing way to floss!

Great Product
Excellent product. My dentist asked that I get a water flosser - but did not say which brand. I purchased this based on the reviews and I am very glad that I did - it works well, cleans my teeth in the hard to get spaces, great water capacity - size is perfect for my sink area. I love this product.

Worthwhile long term purchase.
I bought this back in 2019 and it’s still working effectively today. My oral hygiene journey has been sporadic at best but lately I’ve been trying to be better and I can say that the claims that it reduces gum bleeding are true accurate. I tried traditional flossing for the first time in a while recently and did not bleed at all. Independent studies show that the claims that it’s 2x more effective than string flossing are overblown but they do hold that water pic flossers(approved by the ADA) are at least AS effective as string flossing when used properly, if not marginally better. Pros: It’s easier, more comfortable, and faster(for me) to use than traditional flossing. It does reduce gum bleeding, and the product has lasted for at least 6 full years without a noticeable decline in pressure /functionality. All these mean that I actually remember to use it which is the biggest benefit for me. Cons: it leaks. I don’t know from where but if I keep water in the reservoir it creates a puddle now. It’s manageable if you fully empty it each time but it is somewhat annoying. I don’t recall if this has always been an issue. It’s louder than I would like it to be. Also an important consideration when using is how you plan to keep the machine sanitary because this can be way less sanitary than string flossing if you don’t clean it regularly. All in all, a worthwhile long term purchase for me.

Exactly what I asked for
Effective. I don't ever need to refill to finish a flossing. The only knock is the size (which I'm fortunate enough to have room set aside for) and how loud it is. It's louder than I expected but I suppose that's how you know it's got the power you need! It also pleasantly does not slide around with all the vibrating. I wouldn't want to drop it from counter height but the build quality feels solid. Satisfied so far!

Great flosser, great size and does a great job for such a small unit.
This is a really great water flosser, It is my second order of this brand and it works wonderfully for getting those hard to reach places in the mouth. Leaves a nice, clean sparkling feel and does a good job of it. It is a small unit but I have not discovered any water leakage while using it. It comes with several different tips for different usage, like with braces or orthodontics. I have a small bathroom and it doesn't take up much counter space. This unit is quieter than some brands I have owned in the past and I recommend it,

Perfect!
We love this! Great power and makes my mouth feel so clean! I would recommend not starting on 10, especially if you have more sensitive gums and or gingivitis. Having inflamed gums and using this treatment on HIGH would not feel good. But I do 100% recommend this device for aiding in the repair of gingivitis, especially if you are not an avid flosser. This is simple and easy to use and the feeling after words is just the best!

Well worth the money and works beautifully!!
I ordered after trying another one that didn't work so well. This Waterpik is so easy to use and was even easier to incorporate into my daily routine. The heads given really work well and my teeth feel so clean after. I especially like the Pik Pocket tip to get underneath the gum line to rinse out small pockets. I highly recommend this product!!

Excellent product. Works well
Excellent product. Does not need batteries. Portable if you have plug in. Small and light. Excellent power. Seems to be durable. Holds about one cup of water so it lasts three uses or so.
