    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!

    Bought this to help my 10-year-old with cleaning braces and expander, as well as his teeth, since he can't really floss very well with regular floss. But we can all use it in our family.

    Waterpik has a good name/rep, so that was why I chose it, even though there are plenty of less expensive water flossers to choose from.

    I like that this has a large reservoir so you don't usually have to refill it unless you're spending an extra-long time on flossing, or if you're using it at the higher settings. I figured a plug-in might have better power than battery operated ones. I like the sturdiness of the unit as it sits- I have no worries about it tipping over even when empty, even when my kids are using it. It's easy enough to move it closer to the sink if you need to and then move it back after you're done.

    There is a power switch to turn the main unit on and another switch to start the water spraying out of the head. The sprayer pauses every 30 seconds or so to help you keep track of how long you're using it.

    Be forewarned, there will be water sprayed on the wall, ceiling, floor, other ppl nearby, mirror, etc, as kids (and adults) get used to keeping the flosser head in their mouth while the water is turned on, and turning the water off before taking it out of their mouth. He still accidentally sprays things from time to time (after 2 months) but mostly has it under control. You can't really look in the mirror to use it- the water will run/spray everywhere. Keep your head down, mouth open, and go by feel around your teeth and gums. It's gets easier the more you use it.

    My son has worked his way up to level 6 now, which amazes me because I can't stand it on that high. But he sees a big difference in the amount of food particles that come out on the higher setting versus the lower setting. I think it's helping keep things cleaner than regular flossing. I would advise starting on the lowest setting and working your way up as needed.

    There were 6 heads with the unit, so we all get to have our own, plus he uses the orthodontic head. I did have to buy a separate case to keep them organized.

    Overall, I think this is a great investment to help take better care of your teeth and oral health in general. 5 stars!

    For those that don't like reading, I'll cut to the chase before offering some background.

    This is my second water flosser. (See below.). But simply put, this is the best investment in dental hygiene I've ever made. Period. I'll never be without one again.

    Background. During some recent dental work (some cavities crept in), my (new) dentist pointed out that I wasn't being as effective with brushing as I needed to be. He did two things. First, he taught me (at 73) how to brush more effectively around my gum lines using a soft bristle G.U.M. brush that has uneven bristle surface (not flat cut, but some tiny fine bristles sticking up from the flat surface).

    We reviewed flossing. But flossing has always been challenging for me because I have a smaller mouth (for a man) with some crowding in my teeth. It's hard for me to get my hands holding floss in there. I bought some of the little plastic handles with a fork at the end with floss between the tongs. They make flossing easy, but even still, it doesn't work 100%.

    Then he asked if I had a Waterpik. I said, "No, but I'll buy one tonight."

    In in the interest of saving some bucks, I first bought a portable, cordless model from another maker (reviewed elsewhere). It was a good unit, at least for experienced water flossers who travel. But it wasn't right for me. Only two water pressure levels -- fast and faster -- hard to hold and direct the water stream, etc.

    So I returned it, added $20 and bought this one.

    BEST DENTAL HYGIENE PURCHASE I'VE EVER MADE.

    The small hand water controller unit on the hose allows me to turn the water flow off when I need to and MUCH more precise direction of water at the gum lines and between teeth without water flying all over the bathroom. I was able to start with a very slow flow (2 - 3) as I learned the technique. I'm now up to 5 - 6.

    The larger (by 100%) water reservoir means I can take my time. The way the basic tips are bent make it very easy to direct carefully.

    There are only two minor "I wish this were different" issues. One, it's noisy. Not horrible, but still a bit loud. But I'm used to that now.

    Second, I wish the "handle water flow on/off" was a push button instead of a slide switch. The switch is a little tricky to push down when the handle is wet and I'm leaning over the sink. But again, it's a MINOR issue. I'm happy it has the separate control switch so I can pause the water flow with the main pump running at any time, including before I begin and when I'm finished before removing the tip from my mouth.

    I'm using this device multiple times per day. After every meal, before I brush, and sometimes even just after a snack without brushing. I capture the water in a plugged sink to examine it before draining down the drain. I gotta say, I'm sometimes amazed at how much food washes out.

    Then I brush, and my teeth feel cleaner than they ever have after just brushing.
