Powerful,easy to use, and really works
This water flosser surprised me in the best way. The water pressure is strong — not like those weak gadgets that only tickle your gums. The battery lasts a long time, it’s comfortable to hold, and the size is perfect for everyday use or travel. It’s a bit noisy, but honestly, I’d be noisy too if I cleaned between teeth this well. After just a couple of days, you can really feel the difference — everything feels cleaner and fresher, almost like after a dental appointment. The tips are easy to swap, no leaks, no weird issues. For the price, it’s an awesome tool that actually does what it promises. If you’re unsure — just get it. Your teeth will thank you, and your dentist might miss the extra business.

Easy to Use Great Results
I received this water flosser 10/17/25 and began using it after I charged it overnight. I decided to wait until after my dental cleaning appointment to write a review so I could get feedback from the hygienist regarding the effectiveness of removing plaque. At my dental appointment on 12/11/25, the hygienist was pleased because there was very little plaque buildup on my teeth. Her only recommendation was to use the flosser on medium speed because she said high could cause damage to the gum tissue. Here are the PROS and CONS: PROS: It's very easy to fill the tank with water. (I use filtered water that I store in a water bottle on the counter) It holds a charge for two to three weeks. It's easy to use and makes my teeth feel really clean. It comes with five cleaning attachments: 2 regular water sprayers, 1 plaque removal tool, 1 tool for braces, and a tongue cleaner. I keep the tip covered with a toothbrush cover when not in use. CONS: It is a bit messy as water flows out of your mouth and on the handle which makes it slippery. Overall, I'm happy with the product and the results.

Best water flosser
This is the best water flosser that I have ever tried. I have been using a water flosser every day for the past seven years. I have used multiple brands and models, including the leading name brand. My last water flosser was an expensive brand, but it gave up the ghost after just a few months. This summer, I decided to purchase the Onlyone water flosser on sale and give it a try. It has been WONDERFUL. The biggest problem with other brands was that the battery always ran down after just a few days. Secondly, the other brands would trap water behind the reservoir and develop cracks in the tank, causing issues with water pressure while flossing, and leaking water puddles onto the bathroom counter overnight! Finally, the tank was always running out of water before I finished flossing, so I had to fill it up repeatedly. However, this brand fixes EVERY SINGLE PROBLEM. The battery easily lasts 3 weeks to one month on a single charge. Water never gets trapped behind the reservoir, and I have not seen any cracks develop in the tank after several months of use. The tank is larger, and I am easily able to finish flossing on a single fill. Two other bonuses for the Onlyone water flosser: 1) The suction power is stronger, so it cleans teeth more efficiently and doesn't leave behind water residue at the bottom of the tank. 2) The tips are slightly narrower than other brands. At first I was disappointed, but then I discovered that it is easier to reach difficult angles at back of my mouth. The narrower tips are also more efficient at cleaning food and plaque. A huge plus! The Onlyone water flosser is by far the best water flosser that I ever purchased. Amazing product for a great price.

Get this one instead of the 80 dollar one!
Good water capacity, great battery life. I didn't need all the nozzles, as I don't have orthodontic work, but the standard tip works well. The angle of the nozzle is adjustable through twisting. The settings work well! My mouth feels way cleaner than dental floss alone. Definitely a must have in the home. I've only had to do the initial prior to first use charge so far! The machine has a little noise, but it fairly quiet. Once you get used to using a water flosser, there is little to no splashing. Fantastic quality for the price.

Very easy to assemble and disassemble; super for traveling
This flosser is very easy to assemble and disassemble. I brought it for traveling and it’s super convenient, portable size and space. A full charge can last three or more weeks of use. I have used it for three months, no water leak. Very functional and clean.

Good unit
I have been reluctant to use a portable water flower but this little machine has turned me around. It is powerful and does a good job, I believe, in getting my teeth cleaner than just plain flossing. My husband has this same unit and it seems to be holding well. My only complaint is that when I went to look for additional replacement picks, they only sell them in a multi-pack and include a bunch of additional picks that I don’t need and never will use. I think that is so wrong to force us to buy something we don’t need. Just a ploy to get our money.
