Review: Best water pick for permanent retainer wearers! - I genuinely cannot believe I waited this long to get a Waterpik. This thing has completely upgraded my dental routine and made my mouth feel cleaner than regular floss ever has. The Waterpik Aquarius is powerful, easy to use, and honestly makes my teeth feel like I just left the dentist every single time. The rotating tip is a game changer because it easily reaches every area of my mouth, especially those annoying back teeth that are hard to floss properly. I also love the built-in timer and pacer because it helps make sure I’m actually spending enough time cleaning every section instead of rushing through it. What impressed me most is how fresh and clean my mouth feels afterward. My gums feel healthier, my teeth feel smoother, and it removes so much more than traditional floss alone. It’s also amazing for anyone with sensitive gums, dental work, or braces because it’s thorough without being harsh. The large water reservoir is super convenient, and having multiple flossing tips included makes it perfect for different dental needs or multiple people in the household. You can absolutely tell this was designed with both effectiveness and comfort in mind. At this point, I honestly never want to go back to regular flossing alone. This has become one of those products that makes such a noticeable difference that you wonder how you ever lived without it!
Review: 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 desertcart, 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 desertcart gives the absolute best price for the WaterPik. Of course it arrived within days and like all other products has a great return policy.

### ⭐⭐⭐⭐⭐ Make no Mistake - This is a Better Waterpik
*by C***N on February 10, 2015*

Looking at the reviews, there seems to be a consistent effort by what I take are some owners of the venerable Waterpik WP-100 Ultra to trash this new model and portrait it as inferior to the WP-100. I don't think this is the case, the WP-660 is an improvement over the WP-100 in many ways and I'll tell you why later. The funny thing is that when I bought my WP-100 about six years ago, there were some reviews from what I take were owners of the revered WP-60 Classic trashing the WP-100. I take some people prefer the old to the new and that's OK. But I think some reviewers are being unfair to the Aquarius I owned a WP-100 that lasted for little over six years, used almost every day by two people, those are a lot of days so the WP-100 is an outstanding product. I did have to replace the water reservoir once due to the cheap rubber valve mechanism -improved on the Aquarius as you will see- that failed after three years of use and started leaking. Also, the hook for the handle broke -also improved on the Aquarius- and it was very difficult if not impossible to hang the handle onto the Waterpik body, I had to makeshift a Velcro handle that looked terrible. Googleing around I was surprised to find that this is a common issue with the WP-100, some owners have replaced the entire unit just because of a broken handle as there is no spare part available from Waterpik. Boomer But other than those two issues, my Ultra worked flawlessly, I never had to replace the hose or the handle as some owners had to, the on-off switch never failed and it worked the same way it was when new until an accident damaged the power-cord and it stopped working. Given its state with the handle hook and its age, I thought about self-repairing it but then I decided it was time for a new unit. At first and reading all those pro-WP-100 anti-WP-660 reviews I was tempted to get another WP-100, but the price of the Aquarius was about the same as the Ultra so I decided to give it a try I'm glad I did. The first thing you notice with the Aquarius is its modern look and high quality materials, all white and clear, and gorgeous, a significant design improvement over the WP-100. It is also lighter, which some can argue is a good thing -like me- and some can argue it is a bad thing because it "feels" cheap, which is also a valid point. The important thing is that its weight doesn't compromise its operation in any way, it won't tip-off when used nor will slide or be unstable, it is just lighter. It might be due to the use of cheaper materials on the pump as some have argued here, or just lighter materials, an overall technological improvement rather than cheapening the unit off. I guess time will tell which one is more durable, or we will have to open both units and compare its guts to get a final answer. So, why is the Aquarius better than the WP-100, other than it looks? -The WP-660 is less noisy and runs smother than the WP-100, you notice this right away. This with no compromise to the water pressure, the pressure is steady, as or more powerful than the WP-100 but it runs better, it sounds less stressed. Same or better results with less noise. -The hook for the handle was replaced by a sturdier piece and a different design to hold the handle, which reduces the pressure on the piece. With the WP-100, it was very easy to push the handle all the way down the hook, either by accident or just because of its design, stressing the hook and eventually breaking it; there was nothing to stop the handle to slide all the way down. As said, mine broke. That was a poor design, fixed on the Aquarius; now you just put the handle on the holder, it cannot be pushed all the way down. Some have argued that makes it difficult to handle the hose, but I didn't find any issues, the hose juts hang there by simple gravity, it doesn't tangle or interfere with the unit in any way -The reservoir valve was replaced by a metal spring mechanism. This was a another design flaw of the WP-100, its reservoir valve consist of a rubber piece, very cheap in my opinion, which eventually gives up and start leaking after a few years. As said before, the only way to fix it is by buying an entire new reservoir as the little rubber piece is not available alone, which means not only paying way more but also a waste of resources. In contrast, the WP-660 has a stainless steel spring with a plastic cap, that appears way more durable and also a much better and higher quality solution. Only time will tell but it seems it will last longer than the one in the WP-100 -The knob to graduate the pressure is easier to operate. The WP-100 has a hole to put both fingers in, on the Aquarius is a protruding knob, very easy to reach and to manipulate, way better I think, easier to find when in use if needed. And also more ergonomic -The Aquarius handle has an on-off switch that actually works. The WP-100 has that dreadful push button on the handle that you need to press constantly to stop the flow of water, doesn't stop it completely and also causes the Waterpik to make a noise like the pump is being damaged while the pressure is reverted. Not good at all, it was a poor solution at best, a useless feature at worst, it just didn't work. On the WP-660, there is an actual on-off button; in fact the correct way to operate this new Waterpik is to turn it on the base first, then turn it on via the handle when you already have the tip inside your mouth ready to go, the water doesn't come out unless you turn the handle on. This is much better than having to reach the switch on the base unit with the tip in your mouth or having to hold into the appalling pressure cutting button on the handle and then release it. All this while water was still coming out of the tip as the button didn't cut the water flow completely. -The pace timer. This feature is non-existent on the Ultra, and I realized it is very helpful. I use the Waterpik first on the upper section of the mouth, outside-inside and then move to the lower section, in-out and I'm done. At a pressure level of 8, the water in the reservoir, at full capacity, should last little less than 90 seconds. The Aquarius will give you a very short flow pause at 30 seconds of use and another at 60 seconds, this is good to pace your cleaning as it should take about 30 seconds to clean each part of the mouth, up and down, and then you have an extra 20 seconds to touch-up. This avoids you having to be periodically peaking over to the reservoir to see how much water is left and instead allow you to concentrate on the cleaning and doing the job properly -The reservoir cover is now part of the unit. If you are like my mother in law that misplaces everything - sorry mom, I still love you-, chances are you have misplaced the reservoir cover of the WP-100 (as my mother in law did). This cover also contains the tips so it can be kind of an inconvenience to lose it. On the WP-660, the cover is attached with a hinge mechanism to the body of the Waterpik, no way to lose it. The tips are now stored on the unit itself, behind the reservoir The rest is about the same as the WP-100, it comes with a bunch of tips from which you will probably only use the classic jet, and a 3 years warranty. It also includes a gum massaging mode which is pointless as you can achieve the same results by regulating the pressure knob. One disadvantage to the WP-100 is that you can only store two tips on the unit and not four, but again if you are like me that use only one, this is not an issue. But it might be for some users, if you have braces for example or like to regularly use the one designed for root canal maintenance (the Pik Pocket). One thing that was bad on the WP-100 and remain as bad on the WP-660 is cable management, there is no place to wrap the cable or at least a Velcro band included to deal with the cable, this lack of cable management is in part responsible for the damage to my WP-100 power cord, the cord is just hanging there. A needed improvement for the next design, please take note Waterpik Overall, I see no disadvantages when compared with the WP-100 and instead see many advantages. Until the unit has more years in the market, speculating about its durability without real facts is pointless at this time, so far the Aquarius works the same or better than the Ultra so it's higher price is justifiable. And you can even get a good deal and get it at the same price or a little cheaper than the Ultra, which is a real bargain
