no way to keep it inactive
So, I really like this water flosser for its convenience and ease of use. The only down side is, once its charged, there is no way to turn it off power, for instance, if you're traveling and have it in your luggage, there is no way to prevent the "on" button from being pushed. I do remove the top from the reservoir when traveling but still, it can easily be turned on and making noise/wasting a charge while in luggage.
