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

Bought a second one for a different houses. First one is over 7 years old and going well. The trick is to use good rechargeable battery. Fujitsu. It's better than my waterpik and last longer on trips. Easily last 2 weeks for 2 adults. This uses only 2 AA battery, where the Waterpik used 3 AAA (and did not feel as strong). Easy to clean was also what I had like. Just pull it apart and you can reach everything. The only minor complain is the cap to the battery housing is a little hard to twist off. I guess that offset the tight seal as I have never had water issues or seepage into the batter compartment and compact. It also stands upright and stable, don't wobble and easily get knock over. Folding down to a small cylinder help when travelling.

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.

Does the job. Very powerful. But cap over the water reservoir detaches easily. Hard to snap back on and very tiny. Manuf could make this part bigger and more secure.

I purchased this flosser in February and I loved it so much for travel and home. However it has just stopped working in the last month. This is so unacceptable - I welcome assistance with a replacement but it doesn’t seem to be available on the website! Sooo disappointing!!!!

Good quality and easy to use. Relatively quiet compared to the similar stuff. Comfortable to use and it functions really well.

I keep buying this same model every 7 years or so. These are the best portable irrigators. I prefer these for the AA batteries and not rechargeable so that they can pack in checked luggage. When used with NiMH they have plenty of power to clean your teeth. Highly recommend this.

I appreciate the cordless appliance. Seems to do the job. This is the second one I have purchased. It's a worthwhile investment.

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.
