Water Flosser for Travel, Cordless Portable Oral Irrigator with Two Water Pressure Settings, Collapsible Water Tank - EW-DJ11​-A

I bought this water flosser specifically for travel, and it has been fantastic. The collapsible design is brilliant—it shrinks down to a compact size that easily slides into a toiletry bag. Despite being battery-operated and portable, the two water pressure settings are surprisingly powerful and leave my teeth feeling completely clean. Highly recommend if you're on the go a lot!

Small and compact but holds enough water for one use. Battery last a while and quality is great.

Pretty good, but not as powerful as the non-travel counterparts. The AA battery is both nice and a drawback, as it limits the amount of water pressure it can push through. The enclosure is also a compromise. The water tank doesn't really lock in place, it latches past a detent on the body but is free to move around beyond that. Pretty good product but definitely travel oriented.

Just purchased this to replace a thirteen year old, earlier model of the same Panasonic water flosser. The old one still worked, but wife said the inside of the tank was too gross looking. Holds enough water for me for a single session without refilling. Water pressure is good (as it has been with the old one for the last 13 years). I like the AA battery usage (I use Eneloop rechargables in it, which will last for months without recharging), as I doubt any built-in rechargeable battery would last 13 years. Reading reviews complaining about a flooded battery compartment, and looking at the device design as an engineer, I notice that if the tank were to be compressed closed with any water left in it at all, this could force water into the battery compartment and of course cause a device failure. So do not compress the tank without first opening the fill door and shaking out any water in it. Also, to keep the tank from growing mold I always store the device uncollapsed, with fill door open and water shaken out. Hope this new one lasts as long as it predecessor.

This is a terrible product that has a design defect whereby the battery case is submerged in water and the seal is not water proof. Three times in a row by batteries got flooded and died and now the product won't work at all. Good luck trying to contact Panasonic to make a warranty claim. I spent $50 on a product that is unusable garbage after only 2 weeks of use. Trash

I think swishing water around in my mouth is about as effective as this thing is, given how low the pressure is at the nozzle tip. I commend them for finding a way to make one that can be put into checked baggage (using old-style, disposable alkaline batteries, which of course has its own drawback). But the pump is disappointingly weak. I had purchased a different travel water flosser here at Amazon, but it had two other faults: • The rechargeable lithium ion batteries were not removable, so the whole thing had to go in my carry-on bag due to FAA safety regulations. • It physically broke when I was putting the water tank back on.

I’ve used a lot of travel flossers, and Panasonic is definitely the best. It’s incredibly compact but still manages to have a large enough water tank so you aren't constantly refilling it. I actually have a Sonicare travel water flosser from Costco that I use at home, but this Panasonic one is the only one I ever pack for trips. Highly recommend if you need something portable that actually works well!

I have tried no fewer than 10 water flossers in my life. This is my favorite for convenience, portability, water stream power, how it fits in my hand, and size. It about 2 years using it twice a day, the batteries last about 3 weeks, and it needs to be cleaned every 1-2 weeks. ( germs from your dirty mouth and the bathroom build up.) I wish it had a rechargeable option, and I wish it was easier to disassemble for cleaning. Again I have not found anything I liked better.
