Inexpensive, compact, effective
Inexpensive, compact, effective and very easy to fill - this is a very good travel water flosser. Good design. I’d choose it again.

Great for travel
I didn't want to take my big water flosser on a trip to visit family so this was perfect - kept it in my backpack so I could clean my teeth on the plane and get my Invisaligns in without brushing - I could wait till I was off the plane for that. I did have to refill it once to get all my teeth inside and out thoroughly but that is minor given how nice and compact this is. The charge lasted the entire 6 days I was gone and I used it 3-4 times a day.

Works well but needs improvement.
This water flosser works well and is totally portable for travel if needed. But, there are a few things that need improvement. First, the power button is located in a terrible place, meaning that if you aren't careful and pick up the device with your fingers in the wrong position, it will turn on and squirt water everywhere, possibly on your face or in your eyes. This leads me to a related issue: there is no lock or safety button to disable the power button, so it's always ready to fire off, even when you're trying to fill the reservoir with water. Overall though, with these two flaws, the flosser does its job, and its size and weight are a huge plus.

A powerful, compact flosser that checks all the boxes
This flosser has a MUCH smaller footprint of any flosser I have ever used, which is most important when traveling. It also is nearly as powerful as the highest power on a plug-in flosser, so should be more than adequate for most; it has two lower speeds for those with more sensitive gums, and a pulse mode as well. All work easily and it also is easy to change modes when desired. The battery holds a charge longer than other portable flossers and comes with a USB-C cable for easy charging. It not only has a small footprint, but the water chamber is designed to hold enough water for a basic flossing, and may need one refill for a thorough flossing experience. It even has a clever way to store one of the flossing heads inside the water chamber, and comes with a bag that stores everything when traveling. It runs quieter than other portable and plug-in flossers. From a flossing perspective, it removes most debris from between teeth, including berry seeds, although it has trouble with stringy meat (as does any other water flosser), which requires a string flosser most of the time. And, of course, it does a great job of massaging the gums.

A travel flosser I will actually take and use
This is the third travel flosser I have had over the years. The first two were either too heavy/bulky or too inconvenient to use and ended up staying in a drawer. This little one is great. I used it at home for a few days when I was between regular-sized ones, so it had a trial before hitting the road. It is small, so you will have to refill at least once per session, but that is very easily done through the flap at the top - no need to remove the tank. It is easy to hold, turn on/off, and its power is adequate. The tip is easy to eject and stores inside the water tank for efficient travel! The charging port has a flap to protect it, so there is not a little rubber piece to get lost or forgotten. There’s a cloth drawstring sack included. I can’t report yet on how long the charge will hold. Very happy with this purchase!

Great for travel and everyday use
I love this flosser!! This flosser is small enough to pack but big enough for everyday use. The quality is outstanding! There are three tips included and they all serve a separate role from flossing to cleaning to tongue cleaning. I love the feel of this flosser in my gums; it’s not too harsh. This product is not bulky so it fits in your hand perfectly, great design!!

Convenient for travel
Water will leak if it’s not in an upright position. A full fill up will pretty much get everything out of my braces after eating lunch. Buttons are also pretty sensitive. It does come with various attachments that make it’s easy to use and get your teeth pretty clean. The durability on the battery is pretty good. I’ve only charged it once after about 4/5 uses. Just charged it to be on the safe side.

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.

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.

This is a neat device, I've been using it on and off for about 3 months. It is effective but you I do get a better result from more traditional flossing. The benefit for me is normal flossing tends to end up with my gums bleeding so use this when I'm travelling with work. Single charge lasts the 2 or 3 days I am away before I charge it again, hasn't run out on me yet.
