T40 Travel Water Flosser for Teeth, Cordless Portable Design, Black

Excellent device and super easy to travel with and feel like you're getting a full sized water flosser in a mini sized travel pack. There are a number of settings with a starter level to help your teeth and gums get used to the pressure without damaging the gums. The size of the COSLUS is compact enough to take on all your travels. The cordless device is easy to charge and lasts a long time. I highly recommend this traveler model for all your travel needs. I went to Japan with this device for two weeks and performed like a champ! The water capacity is perfect for my mouth and while it may seem small, you can refill it effortlessly. By far the best value for the money spent. I would buy again or even as a gift!

Perfect little travel water flosser! I ordered this last minute for a two week European trip and it was perfect. It arrived in less than 24 hours of ordering. It’s compact, yet holds enough water to do a thorough once-over of my teeth. I refill it a second time when I wanted a extra thorough cleaning. It hasn’t needed a recharge yet and I’ve used it a few times a day for a month or so now. It’s so much better than my older travel water flosser which was bulkier and heavy and took AA batteries that wore out quickly and depleted the water pressure gradually - this one maintains the full pressure despite not having been recently charged up. What an improvement! I also really like the pink/purple color I got - it’s cute and matches my bathroom’s color scheme.

I love it. It lasts a long time, very convenient for travel since it's small & no electric converter is needed. It works great. I wish there's 1 more stronger level 😊. There's no leak. It's perfect for now. I definitely recommend to anyone.

This was a great, compact water flosser that was perfect for travel. Despite its small size, it was surprisingly powerful and allowed you to cycle through several pressure levels, ranging from gentle to full power. I purchased it in September 2025 and had no issues with it for an entire year. Unfortunately, in September 2026, it started repeatedly flashing red as though the battery needed to be charged. The red flashing light will stop after it has been charging for a while, but shortly after using it, the light starts flashing again. I've tried charging it several times and have also tried different USB ports to rule out a charging issue. It will work for a short period, but then the flashing red light returns. I've also tried contacting Product Support, but I keep getting caught in a loop between the Product Support chat screen and Amazon Support. So far, I haven't been able to actually connect with anyone through chat to troubleshoot the issue. Overall, I really liked this water flosser while it worked. It was compact, convenient, and powerful, but unfortunately, after only about a year of use, it appears it's time to replace it.

Perfect for travel. Efficiently powerful, it’s small and perfectly packable. It works very well with plenty of power.

So far so good! I just got it and tried it out and am very happy with this little flosser, especially for the price! I am traveling internationally soon and I pack LIGHT! So I am glad to have a small device. I am accustomed to a large name brand flosser at home so I don't really have a learning curve. I find it easy to use and the buttons are a good location on the handle. I have to refill for complete flossing but it is compact unit after all. Let's see how it holds up . . . but for the very low price, I manage expectations accordingly.

I ordered this on day 1 and it arrived early day 2 of a 6 day trip. I did not pack too tight, so I knew I could fit this into my toiletry bag. It was so easy to set up and use. Good oral hygiene is something I take seriously because I had braces 2 times and Invisalign recently. My teeth are an investment and my smile is important to me. More than that, I hate feeling food stuck between my teeth. This flosser had good pressure, had several nozzle types to choose from, is wireless, and is really small/portable.

I am someone who is not a flosser and uses a water pick daily. This was the perfect item to add to my travels. Easy to set up easy to use and when needed easy to charge. Just as effective as an electric at home waterpick. Overnight, weekend, or weekly plus travels this mini flosser is perfect to have

Súper buena opción para espacios chicos o salir de viaje. No pierde potencia y la pila dura muchísimo. Lo súper recomiendo.

La bateria le dura muchísimo y los niveles son muy agradables. Me encanta.

que paso? por que se cancelo mi compra?

Después de que se terminó la primera carga, lo cargué y dejó de funcionar.

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.
