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.

This great old classic still is essential for dental health - buy it - use it!
In this throwaway society where appliances, especially electronics, are considered obsolete sometimes before the batteries need recharging, it’s amazing to find one product that is still virtually unchanged after over 50 years on the market. It hasn’t needed any upgrades, and is still basically the exact same function and design as it was way back when. I particularly find this gratifying when I just learned, for example, that Apple will be issuing an upgrade on their OS system for their IPhone, which will basically make any of their phones from the 4S and below obsolete, so that, even though yours may work perfectly, technically, you would have to throw it away and spend many hundreds of dollars for a new one! This appliance that has stood the test of time is the WaterPik. I remember my father buying one of the first ones, per his dentist’s recommendation back in the 1960s. In those days there was something about it that seemed almost futuristic. Like something you would see someone using in outer space in a SCI Fi flick. However it’s simple design and function was enormously easy to master, which is a big deal for me back then as little kid! It is also quite uncommon, when it came to devices that supposedly promised some kind of improved health, to find that everything they say about the produce… is true. I remember year after using it, and going from my annual checkup at the dentist, the results were amazing. I stopped using the WaterPik years ago, and just depended on regular brushing and flossing. However now that I’m not such a young kid, even with diligent dental hygiene, you’re gums will begin to do some receding on their own, purely by the evil tyrant known as “aging”. My scores for my gums receding were getting a bit worrisome, in the last few dental checkups, and again my dentist recommended that I should also use a WaterPik. To be honest I was surprised they still made them. I felt, like most everything in the world, these had fallen out of style or favor and we’re no longer used. My dentist however told me they were perhaps one of the best dental hygiene Home Devices ever invented and he was sorry to see that most people didn’t use them anymore. I told him that I flossed religiously, but he told me that the WaterPik gives an extra much needed work-out to the gums keeping them healthy and strong and reducing gum receding. So of course I went right onto Amazon, and found this unit. It was basically the same as I remembered, though they have streamlined the device a bit. Again it was easy to use, and starting with a low pressure number, I quickly got used to the pulsating action and within a week was at the highest level (yes, as “Spinal Tap” guitarist Nigel Tufnel would say: “it goes to eleven!”). The unit is actually a bit quieter than the original with an easier water reservoir system and a coiled hose which makes placement back on its “holster” a lot easier. It also has several holders for each individual pick if more than one of you is using it. Since I’m the only one who uses it, I simply keep the pick itself on the hose unit which fits easily on the hose-holster. Putting it back in its little holder which is situated behind the water reservoir is a little awkward, and frankly if you’re the only one using it there’s no reason to just keep it attached. So on to the punch line. After only six months of use, I went back for my dental checkup, and went through the rating test for gum receding, and found that all my numbers went up 50 to 70%! My dental hygienist, who does the tests, was so excited that she literally ran into the hall to show others, like a proud mother showing off her son’s report card. I feel like a little boy again, and was just a little upset that they no longer give out lollipops as rewards! One thing my dentist and dental hygienist did tell me is that if you use the WaterPik, you should continue to floss, since there are things that the actual floss does between your teeth which a WaterPik cannot. And of course things that the WaterPik can do that flossing doesn’t. So the combination of the two is extremely important. I’m at the age where friends are beginning to tell me about real trouble with their teeth, and how many are getting bridges and implants, and in one case even dentures, since their gums have receded so badly that their original teeth had to be removed (and we’re talking about folks in their late 40’s to early 60’s here, not ancient people). So I cannot stress hard enough how important something like a WaterPik is. And also, how important it is to start this kind of dental hygiene when you are young. For me, especially as you get older, there is nothing more constantly prevalent than when you have bad teeth. I don’t think anything else destroys your quality of life more than trouble with your teeth and the consequences it causes. By the way, after doing a lot of research I have found that Amazon gives the absolute best price for the WaterPik. Of course it arrived within days and like all other products has a great return policy.

Mostly good experience, but the noise is loud and the slide button is hard to feel while using
It's taken me a few days to really get the hang of using this unit, but once I got used to it, I really like it. It's a bit noisy when you run it, but it does a great job of cleaning between your teeth. You still need to use traditional floss to complete your dental care routine, but the water flosser does a great job of getting rid of the soft plaque and food particles you may have. It also feels great on my gums. I've gradually upped the setting from '5' to '8', and after having it squirt a few times into the corner of my inside mouth, I've decided that was strong enough. The assortment of attachments that come with the unit are overwhelming. I decided to start with the attachment that has some bristles on the end of it, and it seems to be a good one for me. I like that the bristles help you figure out where the end is pointed at. It takes some experimenting to figure out how best to use it. I've tried keeping my head in one position while using it on the inside of my gums and the outsides of my gums. I still don't have a consistent method, but just kind of do whatever keeps the water from running into my beard as best I can. Besides the noise, the other annoyance I've found is that the slide button on the wand is a bit tough to feel and figure out how to slide it to turn the unit on and off. I tend to do one side of my mouth, then turn the wand off while I angle my head another way to do the other side of my mouth. The first few times I was doing this, while feeling for the button I'd end up accidentally hitting the button that disconnects the nozzle attachment from the wand, making a mess. I've learned to keep my thumb on the off/on slide button so I can quickly turn it off when I want to.

Impressive Results!
Works! Absolutely worth the investment to bring my gums back to health. My next dental visit, the hygenist was surprised by how much better my gums and teeth looked. Not a travel-friendly kit, but the machine was easy to set up and use.

Works very well for daily use. This has replaced a rechargeable unit with a bad battery. Wide range of pressure adjustment with plenty of water capacity.

The Waterpik Aquarius Water Flosser has been such a helpful addition to our family’s dental routine. With 10 pressure settings, everyone from my husband to the kids can find their perfect level - no more complaints about flossing being too hard or annoying! I also love that it comes with seven different tips, so we can each have our own, and it works great for different needs. Whether it’s braces, sensitive gums, or just a good deep clean, this flosser handles it all. The tank is a good size and lasts long enough for a full session without needing a refill. It’s not the quietest gadget in the world, but honestly, that’s a small price to pay for how clean my teeth feel after using it. It’s so much easier than regular floss, and it feels like a little mini spa treatment for your gums. Definitely worth it for the whole family!
