I purchased the Waterpik Aquarius Professional Water Flosser in January 2018 after my dentist recommended it. I waited until July to provide a review, because I wanted to wait until I had a follow-up visit with my dentist. When they made the recommendation, they informed me that I was beginning to get some plaque buildup, which might require a deep cleaning. They suggested that I try the Waterpik for six months and come back for a follow-up appointment. I just had the visit, and there was a marked improvement, and no need for deep cleaning. I have used the device daily for the last six months, and now feel confident that it really does help improve your oral health. It is also (for me, at least) very pleasant to use. While it is noisy, my teeth feel that kind of clean after visiting the dental hygienist after every use. I further recommend the product because of the great customer care from Waterpik. The reservoir on my device recently started leaking. I first went to the Amazon site to see if I could buy a replacement, and it isn't offered. I then went to the Waterpik site, and they don't offer replacement tanks for this model either, so I started an online chat with them. They asked a few simple questions, and then offered to send an entire new unit to me at no cost. Really great customer service was instant, and they clearly support their products aftermarket. Following is the link to the model I bought:  Waterpik Aquarius Professional Water Flosser Designer Series, White, WP-670Read more

My Waterpik 670 stopped working in 4 months and Waterpik refused to replace or repair it. Waterpik claims it comes with a 3 year warranty but does not honor the warranty. The customer service is poor and they give you every excuse they can find. This is an expensive product but made very poorly. Very disappointing, I will not buy a Watepik again! Read more

This was our second Waterpik, we loved it when it worked! Our first Waterpik, Water Flosser WP-662 was purchased on August 22, 2017 and it lasted until the beginning of April 2019, lasting just over 19 months until it just quit working, the motor would no longer turn on. We thought 19 months was a short lifespan but didn't feel like following up with any warranty action so simply purchased another one, Water Flosser WP-672, on April 11, 2019. Was just as happy with the flosser as the first one, but tonight, September 8, 2019, went to use it and the same problem as the first one, the motor no longer works, so not quite 5 months!. We do use GE surge protectors in addition to the standard GFI protection on the bathroom plug and the other devices plugged in are still working. I will be calling about the warranty on this one, so will update on the results of that. Just overall disappointed as we like it and hate having to now experiment with other brands to find one we like as much. Read more

Awesome and works great. Kind of upset that Walgreeens and Walmart have it finish much cheaper. Read more

Excellent quality and SO much easier than flossing! Tips can go in the dishwasher. The unit is easy to operate.- Other reviews have mentioned the lines getting dirty from standing water. When you're done using it, if you'll hold the unit up in the air (about shoulder height) and the wand down in the sink all the water will run out of the coiled line. Thank you gravity! You won't have any water in the lines if you drain the line this way after each use.- Others have also mentioned the lines blowing out, well.... these things are like mini pressure washers. If you leave the pump turned on and the valve turned off the pressure has no way to escape and you're going to blow the line just like you would on a water hose or pressure washer. Read more

Received this New Waterpik Aquarius Professional Water Flosser...on September 7, 2017 and today, January 10, 2018 the motor just gave out. My previous Water Pick Water Flosser lasted 5 years and did not pay as much as my new more expensive recent broken device. Read more

The unit stopped working after 1 use. I called waterpic directly.they will replace the unit in a time frame of 5 to 10 business days. Amazon delivered the product when I purchased it the next day. Don't go to the manufacturer for issues as directed in their packaging. Amazon resolves issues immediately. Read more

I have never had a problem with plaque. I came back to the U.S. from two years in West Africa, and my dentist looked at my teeth and said I have no plaque on my teeth, BUT they are cracked! I am a person who eats chicken bones down to shards...if I have KFC, there will be a tiny pile of bone shards left on the plate when I'm done. I eat all of the cartilage, then I split the bone and chew all of the marrow out of it...I'm a savage. I'm no longer doing that because I'm mostly plant-based these days (with occasional wine and cigarettes). On Dec. 27th, I had my 3rd molar removed. It had been capped, twice. It hurt for three years because it was cracked, so I had it removed, turns out it was the second healthy tooth I had removed for no reason. WV dentists remove healthy teeth, FYI. I bought this machine to clean around the three isolated teeth I still have. I have three islands that are not easy to floss "between". This is a good-looking appliance! It doesn't take up a lot of room on the sink, and it has three heads with different colors, so I load it up for my husband at bedtime (he grew up in CA with fluoride in his water and has no cracked teeth, but he has a pocket of gingivitis the dentist is watching). He flosses in the morning, but not on the weekends! He has major plaque in his lower teeth when he doesn't floss, I don't have that because my saliva is different, apparently. Read more

I don't floss anymore as this does the job and does it better. Even my wife and daughter like to use it, so due to the fact it came with multiple tips was great. I think I can throw out all the floss as this gets every little bit of food out even after brushing. Read more

Vraiment à posséder pour retirer tout résidus. Vraiment puissant à force maximum, j'ai dû adapter le jet au début. Malgré tout, le fait de posséder les brossettes est encore un plus. Facile à nettoyer, mes gencives se portent mieux. J'avais tester un produit similaire sans fil. La pression n'était suffisante(waterpik wp-30w). Read more

Love this item and it's so easy to use. We got an extra set of accessories for family use. We love the pressure settings for our individually needs. Worth every dollar! Read more

I use this every day and love it! so powerful we always use it between 5-9 (max is 10 and it will wipe your tooth away :P)Haven't used a normal dental floss for a while now! love it Read more

Great, works well, does the job it is supposed to. Thank you. Read more
