I allow myself to summarize the points that I found really convenient for those seeking an easy and discreet humidifier:
a huge + is its autonomy: it lasts well 12h before having to recharge it, it can be left all day or all night without turning handle it. Indispensable. And when the gauge is too low, it goes to sleep automatically. Really convenient.
it diffuses mist, which is very friendly and configurable following what you want to do. You can program at will, including with timer, for not having to take care of! On the other hand one can simply make the trigger at a specific threshold (control 40% to 95%).
It is small, discreet, need only look at the pictures to be convinced! He goes everywhere, next to my desk as in a bathroom shelf.
That, for me these 3 points are enough to justify its purchase and especially its super practical side compared to other bulkier and often noisier humidifiers! A good buy and so simple to use that to quickly forget, super practical!
