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

I bought it for my wife to go to Japan and it worked perfectly for the trip, but it’s not as powerful as our home unit so she went back to our old one when we got home.

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.

This review is for the Panasonic Water Flosser for Travel, the battery operated model. Compared to the previous battery model, this one is quieter and more ergonomic. Unfortunately, it lost all power after five months of intermittent use during travel and the water barely drips out. Total waste of money.

This is the best water flosser I’ve used. I actually like it better than my sonicare. The force of the water is very strong but comfortable. It is noticeable that it gets weaker as the battery starts to fade but I use rechargeable so I just charge them again. And of course this is great for travel. Very good product

This water pick is good but not great.

Panasonic makes quality well designed products and this pick is one of them. It does a great job, has great water capacity, and I love the fact the batteries are AA which won’t fail as long as you have more!!!😊

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.

Works as well as a more traditional countertop unit, except requires two fills to get the job done. A bit more difficult to hold, but not problematic. Easy to clean and dry on the last day of travel. The tank comes off, and the bottom of the tank opens, dry with a towel or give it a shot from a hair dryer. Runs on alkaline batteries, so no problem in checked bags. Really happy Panasonic came up with this.
