Great size for travel, works really well!
Pretty powerful water stream for such a small device! Small water tank, but really refilled of needed. Hold the charge quite a while. The travel pouch is appreciated! Great travel size! Love it!!

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.

Small, great for travel
I travel extensively for my job and needed a mobile WaterPik. This works really well, is small, great battery life, and it has several choices for picks. I need to fill it up twice to get all my teeth but that's not a big deal. The pressure on the highest setting is still not as intense as the plug-in WaterPik, but it's good enough for sure. The branded 'mobile' version of WaterPik is huge, and this is much smaller. It's 4 stars instead of 5 because of two things: the 'on' button placement and you can't lock it off. The 'on' button is exactly where you grip it, so I have **many times** accidentally turned it on, shooting water everywhere. It does not have a way of making sure it does not turn on in your suitcase except by disassembling, and that's a hassle. But-- minor issues with an otherwise solid product.

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!

Works great! Product as described.
Product is lightweight, has the right amount of water capacity and 4 different pressure/speed modes. Great for travel. Battery is rechargeable and it lasts for more than a couple of weeks. Overall, a highly recommended water pick.

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.

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!!

Well Designed
This water flosser is fantastic. I love how small the flosser is which makes it great to take along when traveling. The flosser has great water pressure, which does a great job cleaning my teeth. However, the pressure at times seems to be a bit too much. The flosser is easy to use and it's thoughtfully designed. I would recommend to all who are in need of a water flosser.

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.
