Review (3/5): It seems to work, but it's hard to keep clean.
I like the general idea of the device and so far it has been holding up. However I am starting to question several design decisions. While I like the concept of the uv-light sanitizing, the overall case design is not really maintenance free and unless you completely rinse and dry the toothbrush the entire thing will become dirty. Since it doesn't appear to be made to be exposed to liquids, it's not like you can just rinse it out. So overall keeping the unit clean is maybe more hassle than I asked for. So far it has physically and technically survived two months of international travel, being used twice a day it seems the batteries are good for 30 days. Bottom line: I am going to use it until dies or I find something better. I would however not purchase another one of these.
