Small Size, Big Performance!
I’m very impressed with this little water flosser! It’s compact and perfect for travel, but it’s also powerful enough for everyday use. It comes with several attachments, is easy to use, and does a great job cleaning between my teeth and along my gumline.If you’re looking for a small water flosser that performs really well, I highly recommend this one. Great value for the price!

Fantastic Water Pik
This travel sized water pik is perfect for me because it doesn't take up space on my bathroom counter and is easy to store. It comes with three different picks that you can interchange as needed. I love the ease and simplicity of this pick. It has 4 modes from slow to fast. I usually use mode 2 since my teeth are sensitive. But the water pressure is excellent and gets my teeth & gums feeling fresh & clean. It also helps with my flossing since my teeth are very tight and therefore difficult to use floss. This water floss helps a great deal!A charge lasts quite awhile so you can use this without any annoying cords or wires in the way. I really love this simple yet effective water floss. An excellent investment.

LOVE IT
This mini water flosser is very convenient for travel and everyday oral care. The compact, cordless design makes it easy to pack in a bag, and it doesn’t take up much space in the bathroom either.It has multiple modes, which helps adjust the water pressure depending on comfort level, and it does a good job of cleaning between teeth and around gums. The water tank is small, but that’s expected for a portable model and still works fine for quick use.Overall, this is a practical and travel-friendly oral irrigator that offers solid cleaning performance in a small, easy-to-carry design.

Smallish but great
Great travel flosser. It is a little bulky but still does the job. You can choose the speed of the water and it has a pretty decent capacity.It is cordless and easy to charge. So far it has been very durable with all my travels.
User
Better than advertised.
Wasn't sure what I expected from a small portable flosser but was clearly surprised and happy with this little travel item. Having been pleased with the full-sized flosser from the same manufacturer I thought I would take a chance with this one. Works great, has all the power and features of the full-sized model. Will fit easily in a suitcase. Even comes with a little travel pouch. Glad I made this purchase. One con... tried to register for the warranty but it won't accept the Amazon order number???
User

Saved my gums on an extended trip
This water flosser saved my gums on an extended trip! I returned home with a clean bill of health from my periodontist, who was amazed at how clean my teeth were after a month of traveling.The water reservoir is large enough to do half my mouth, and then I need to refill to do the other half. This good for travel -- the unit is light and small, and refilling once is OK with me. If it had a bigger reservoir, the unit would probably be too big and heavy to want to bring on a trip. There is a good range of pressures, so you can find one that matches your home unit.

🚩🔥**They refuse to register the warranty until they can harvest my IP address.**🔥🚩
I went to register the warranty so it'd be covered if it craps out. Should take 30 seconds. We all need to start speaking up about this.I opened Iron Fox (a privacy-respecting browser, because I'm not interested in being someone's data product) and filled out the form. Name. Order number. The usual. Hit submit, and the site just sat there. Wouldn't budge.Then a little black box popped up at the bottom of the screen and quietly confessed, in plain English:**"ip cannot be obtained"**Why does honoring the warranty depend on whether you can log my IP address?So I read their privacy policy, then I pulled up the actual code behind their homepage and their warranty page. Here's what's running in the background while you "register your warranty":- Microsoft Clarity. Session replay software. Not page views. Not clicks. Actual video recording of your visit, including mouse movements and keystrokes, while you type your name and order number into the form. Someone at COSLUS can rewatch your warranty registration like a TV show.- Meta (Facebook) Pixel. Yes, registering a flosser puts you in Facebook's ad-targeting pool.- TikTok pixel and Pinterest tag. Same deal, two more ad networks.- Google Tag Manager, Google Analytics 4, and six separate Google tracking IDs.- Klaviyo, an email and SMS profile builder tied to your address.- Ahrefs, Loox, Bazaarvoice. SEO and review platforms also collecting data.- A Shopify data-sharing config with "share all events" enabled, scoped to customer address, email, name, phone, and "personal data."That's the surveillance layer. Now the actually weird part.The warranty form on coslus.com does not submit to coslus.com. The visible form posts to a third-party SaaS called PowerfulForm, with hidden fields silently bundling your Shopify customer ID, email, name, and page URL alongside whatever you typed. Meanwhile, the warranty app itself is hardcoded to talk to a server called webapi-cdn.zhcxkj.com, a Chinese-domain endpoint, over plain HTTP, not HTTPS. And the warranty support email isn't @coslus.com. It's a third-party multi-brand claims handler.Your warranty data is going to at least three places that aren't COSLUS, one of which is an unencrypted endpoint on a Chinese domain that any coffee-shop Wi-Fi can read in transit.The page source is also full of Chinese-language developer comments and contains an obfuscated script at the top of every page that hooks into your browser's event loop. None of this is in their privacy policy.One star. Not because the product is bad. For all I know it works fine. One star because "register your warranty" on this site means: get session-recorded, fingerprinted across four ad networks, profiled by six Google tracking IDs, handed off to a third-party claims processor, and have your form data tossed unencrypted at a Chinese dev server. The "ip cannot be obtained" message wasn't a glitch. It was the system trying and failing to log my IP because my browser wouldn't let it. That's the only reason I noticed any of this.And here's the part that should actually piss you off. Every one of those tools, Microsoft Clarity, Meta Pixel, TikTok, Pinterest, Klaviyo, six Google accounts, costs money or engineering time to set up and maintain. They're there because the data they pull out is worth more than what it costs to put them in. Session replay tells advertisers exactly which words on a page made you hesitate. Your email tied to your purchase history tells Klaviyo and Meta what to show you next month so you'll buy something else. Pixel pools let them re-target you across every ad-funded site you visit for the next 90 days. The flosser was the loss leader. **You** are the actual product being sold, to ad networks, to data brokers, to whoever pays. They paid maybe four bucks to manufacture this thing and shipped it to you so they could plug you into a pipeline that earns them money every time you open Instagram, scroll TikTok, or Google a competitor. The "warranty registration" wasn't customer service. It was them confirming the kill, closing the loop between a real human, a verified address, a working email, and a buying pattern. That data is worth multiples of what you paid for the product. Multiply that by every customer who clicks "submit" without asking why a flosser company needs their IP address, and you start to see the business model.

Wow this is powerful !
This oral irrigator is very powerful for its size , I will warn you that it can be very messy , please see the photo above when I first switched the flosser on it shot water right across the room, however once I realised the strength of the water sprouting out ,I really appreciated it’s doing the job it was intended to do.I would suggest when you first use it that the water you use is not too cold , as it did set my teeth on edge but when I use tepid water I am amazed at the debris that washes out from between my teeth even after I have flossed.The water did run out fairly quickly , but that’s to be expected when you consider the force of the water.It’s good that the irrigator is easily recharged and also that you get different nozzles to use -: a standard nozzle , a orthodontic nozzles , plus a tongue scraper and it can all be kept tidy in a drawer string bag also supplied with this flosser.It is also reassuring that you get 24-month warranty for free.

Small, travel size and powerful but I prefer the gentle setting
I use my flosser on a daily basis but it is large and not portable unlike this. Small, travel sized and so ideal for families like mine who floss on a daily basis. After cleaning this out, I filled water into the detachable water tank and slotted it back in, selected a setting and for my initial use I was taken back by the power and coldness. I did stop it immediately and set it on the most gentle setting, after which it was more comfortable to use on my teeth and cleaned them out well. It works just like my main flosser so I am happy with it due to its size and power. I do not use mouthwashes due to conflicting safety advice so I much prefer this as it is plain water and clearly removes particles in between my teeth.
