Review (4/5): OK
I had never used one of these before, so I didn't realize how much of a mess they can make.
First, I saw that the USB charger did not come with a plug. I have plenty, so it wasn't a problem, but it would have been if I hadn't.
The plug that covers the USB port is not attached to the unit and I can see it very easily lost.
There is no hose. The whole unit needs to be picked up and rotated to use this item. I found it a little cumbersome, especially when I couldn't figure out which button was the off one when I was using it.
If you don't get the nozzle in just right it will come off and you will get sprayed. Again, without being able to see the "off", it gets messy.
The water canister isn't very big. I frequently have to fill it twice per use.
All in all, it is an OK unit. I don't have the expectation that it will still be working in a couple of years. But, it is very nice to use now. I will likely buy another WaterPik type device when this breaks. I just don't know if it will be this brand or if I will upgrade to a better one.
