Customers find the water flosser surprisingly powerful and appreciate its portability, being ideal for trips and hiking. The device is easy to assemble and use, particularly in the shower, and its compact size allows it to fit in a side pocket of a work bag. While some customers report it holds its charge for a long time and does a great job cleaning between teeth, others mention it only lasts about 6 months and needs refilling multiple times. Durability is mixed, with some finding it well-built while others report it breaking after a few months.

- Reviewed in the United States on June 3, 2025Color: WhiteVerified PurchaseI couldn't be more pleased with this little flosser. Compact, easy to pack in my backpack, cordless, long battery supply, quick recharge, but most importantly very powerful stream of water and sufficient tank to supply enough water to get the job done. I bought this flosser just before traveling overseas for 2 months and I used it 3-4 a day, never failed and had to recharge just 3 times. Amazing. I just bought a 2nd as a backup for use at home and to keep one in the back pack. I highly recommend it you want one you can even carry in your pants pocket or bag.
- Reviewed in the United States on June 14, 2025Color: WhiteVerified PurchaseI had the travel waterpik and it kept getting moldy in the water cup and you COULD NOT get it clean. I put cup in dishwasher....big mistake. I looked to see what else was out there and I found this travel waterpik. I love it. It's easy to use, I'm not worried about mold bc I separate it yo dry out. Its powerful enough. I only wish it held more water bc I refill it 2 to 4 times each use.
- Reviewed in the United States on June 9, 2025Color: WhiteVerified PurchaseI’ve had this product over a year and have been very happy with it. It works great and is compact.
I think the hardest thing.. which is true of most water flossers is cleaning and drying. I rinse it out with hydrogen peroxide every so often and lay it on paper towels to dry.
In the last month, the bottom part (water reservoir) that slides over the motor part has gotten so tight that I can’t get it off the machine without brute force. I guess the little gasket has expanded but it’s frustrating.
But I like it enough to order a new one if it will last another 15 months I’ll be happy.
- Reviewed in the United States on May 14, 2025Color: WhiteVerified PurchaseAfter my last girl's trip, I realized I need a travel water flosser for compact packing and this one works great! I use mine on the stronger setting so it feels much like the one one I use at home. I was a little disappointed that all the tips do not fit in the storage compartment as noted (but the one tip without rubber will) so I used a small zippered baggie to put them in and they all fit in the drawstring storage bag with ease. I recently started wearing Invisalign and I like to brush and water floss after each meal before I put my trays back in. This gadget is small enough to carry in my purse (I carry a little purse) so it was a win-win. I also like the fact that it is rechargeable instead of just battery operated. I highly recommend this product for anyone looking for a small portable water flosser.

- Reviewed in the United States on July 8, 2025Color: WhiteVerified PurchaseWhy did you pick this product vs others?:
I just threw out this compact water flosser as it suddenly stopped working and would no longer charge. It worked fine for a year and a half and then dead as a doorknob. It’s great to travel with, It ‘s effective and easy to use though (obviously) the small water tank requires filling every use. It also
needs regular cleaning to prevent mold and mildew formation. The integrity of the power supply, whether it be from a weak usb connector port, a battery issue of some sort or a bad on/off switch, these are the most common and most annoying of deficits that force us to dispose of items rather then repair them. I hate it. The technology is great but the build is crappy and so nothing lasts as long as it should. Pity.
- Reviewed in the United States on June 12, 2025Color: WhiteVerified PurchaseThis is fantastic . I’m a water pic addict and dread the time when I leave on a trip without it! I found this on Amazon and had to try it. The water capacity and pressure are superb. It could easily replace my counter top Water Pic. Yes, it works that good. It comes with a brush for polishing and flossing tip. And a “suede” bag for carrying it.
- Reviewed in the United States on July 6, 2025Color: WhiteVerified PurchaseSimple to use. I prefer it over the regular counter top version. Home and travel this is perfect.
- Reviewed in the United States on May 22, 2025Color: WhiteVerified PurchaseI have tried four different Water Flossers from different brands. They all had different flaws and broke within a year of daily use. Some were too bulky for traveling, others had weak water pressure, etc. I bought the last one for travel use. I have been using it off and on for a year now. I like everything about it: the design, the compactness, the sufficient volume of water and strong pressure, the charge lasts a long time. A very convenient Flosser, I find it ideal for use on trips and hiking.

5.0 out of 5 stars Ottima soluzione portatile!
Color: BlackVerified PurchaseNe sono decisamente soddisfatto, uso Idropulsori da molti anni, a casa ho un waterpik e ne ho avuti diversi altri in passato, questo è il primo portatile. E’ potente, ben concepito ed estremamente compatto, chiaramente a scapito del serbatoio che almeno nel mio caso ho bisogno di ricaricare una seconda volta per una buona pulizia, ma è un’operazione di pochi secondi! Il serbatoio si estrae anche completamente per poterlo pulire, il beccuccio si toglie e si mette dentro il serbatoio. E’ impermeabile quindi si può bagnare tranquillamente, la batteria dura parecchio. Inoltre nella confezione ci sono diversi beccucci per tutte le esigenze. Se dura nel tempo e’ praticamente perfetto!
