Review: It works great and Waterpik has great customer service! - This looked like an affordable device, so I got one to try out. It came with enough styluses for a few purposes and people. It's easy to use and the water pressure is impressive. I don't have it on full force because it's pretty strong! When I use it, I can see a lot of little things flowing out that I didn't know were wedged in my teeth or gums. I've been liking this enough to get those rear wisdom teeth that I ordered some new accessories. My rear wisdom teeth are so far back that they're partially hidden. Removing them would be brutal, and flossing them is almost impossible. This really helps. There is a plastic reservoir that acts as a cover for the unit. Lift the "cover", invert it, fill it with water, and plug it into the top. When it's in place, a small valve opens up and water is fed into the unit. I had a problem with mine and when I put water in, it would start slowly streaming out because the valve wouldn't close properly. I'd get water all over the sink. I looked in the back of the instruction manual, and there was an actual 800 number listed for customer support. So many places don't want you calling and only give a website or email address. It was nice to see an actual phone number. I called and was only on hold for a minute before I was talking to someone. I explained the problem and she put me on hold while she looked up the availability of sending me out a new reservoir. It turns out that a small spring closes the valve when the reservoir is not inserted, and the spring was not properly resting in its chamber. While on hold, I noticed it was a little off, reached in with a toothpick, and popped it back in place. That fixed it. When the woman got back to me, I told her I fixed it and didn't need her but thanked her for her great assistance. It was GREAT that the company gave you a number you can call with issues and have people that can help you quickly. That's very good customer service!
Review: Perfect for smaller sink areas - I have a small sink area. A few years ago I was torn between choosing this unit and the rechargeable one mostly because I felt the Nano’s wire would clutter the space even more so I bought Waterpik ION waterflosser but after 2-3 years, it no longer held a charge. I finally replaced it with this NANO and I sincerely hope Waterpik never stops making this size, because it works perfectly for my sink area and even with the wire, it is not a hassle as I expected it to be. The tank holds a decent amount of water (16oz) and it's a huge improvement overall. Yes,the tank is smaller than the larger version and doesn’t have all the buzzers and whistles, but it can be refilled easily. I have no issue with the noise.

## Questions & Answers

**Q: Why is there no cover over the water? That is unsanitary.**
A: There is no cover over the water while you are actively using the water pick.  However, when not in use, the water reservoir is upside down as a cover.  I use a paper towel to dry the inside and everything is covered and remains protected.  It is a good unit and I have been very happy with it.

**Q: How much water does the reservoir hold? Does it need to be refilled during use?**
A: Hello there -

The reservoir holds 15 ounces. How many ounces it will take for each flossing will depend on each person's oral health needs.

**Q: Can you brush your teeth and floss at the same time with the Nano water flosser?**
A: Hello LoRita -

No, this is a water flosser only.

**Q: Is it electrical?**
A: Hello Andy-

The WP-320 Nano water flosser requires an electrical outlet for use.

### ⭐⭐⭐⭐ Does a great job. Would give 5 stars if it wan't so loud and tips snapped in easier
*by 3***2 on May 6, 2024*

Replaced my very old Water Pik (that was similar to the current cordless WP-580 model) with this one because I had to fill it twice to get around all teeth and the amount of water pressure had decreased over the years. I chose the Nano Plus model because it has 5 pressure settings, holds more water than the cordless ones, holds the same amount of water as, and takes up less room on the counter than the Aquarius and ION models, handle is a nice size, it's easy to clean, and also because of the reviews about the Aquarius having some mold issues due to its handle design. I don’t think that’ll be a problem with this one, as there's no rubber on the handle which is sealed, except of course where the tip snaps in at the top. It does have a good seal when the tip is attached correctly. More on that in a minute to address other reviews saying it leaks at that connection. Regarding water pressure, I used my old model on "High" which equates to about "3" on this model which is the pressure I use. 1 & 2 are very low pressure which should be helpful for those with sensitive gums or teeth, but I need to use more pressure to remove food particles from my bridgework, implant and a few deep pockets, and this does a good job removing food particles in those areas that are really hard to get to with floss and brushing. I no longer have to floss two or three times to get food particles out of these problem areas and I can definitely feel the water contacting areas under my gums that I’m unable to contact when I floss. I’m going to try the Pik-pocket tips for my deep pockets. After getting comfortable using it a few times, I can now get around the entire inside and outside of my teeth and spend a few extra seconds on my problem areas with one fill of the reservoir using the #3 pressure. A tip regarding handle leaks where the tip connects mentioned by other reviewers--I'm pretty sure it's because the tip isn't seated properly, which happened to me. You should hear a definite click when you push the tip in. One of the complaints I have about this model is that if you don't know you need to hear that click (and the literature doesn't mention it), you won't know it's not seated properly because it looks like it is, and you have to kind of wiggle it into place to snap it in properly. When properly seated, the tip will either be pointing to the front or the rear of the handle. The other complaint is that it is loud, but so was my previous one, so it's just something I've learned to put up with for better oral hygiene. The handle rotates around the plastic cord at the bottom so you can easily get to your back teeth. Though some reviews mention a tight cord that feels like it could jerk the handle out of your hand, I haven't had that problem. Those situations could be happening because the base is too far away from the sink and the user is having to stretch the cord too far. Regarding the kind of awkward placement of the on/off switch on the handle that some reviewers mention, if you do you back teeth first, then when you rotate the handle to do your front teeth, it’s less awkward to turn the handle off with your thumb. As some reviews mention it doesn't have a top for the reservoir, but I don't mind because you can put the reservoir upside down over the base when done which keeps dust and other bathroom particles out of the reservoir, and I like that it's compact in that position. The reservoir only covers the large motor part—it doesn’t cover the area where the handle, cord and tip are which is probably good so they can air dry. Overall I am pleased with how well it removes food particles from between my teeth and gums that aren’t removed with flossing and brushing.
