Black & Decker Comfort Zone Portable Ultrasonic Humidifier | Turn Bottle into Personal Portable Humidifier - 6 Hour Operation - Whisper Quiet

Purchased for a friend. She was happy with it.

I have two of these to add humidity for my small group of orchid plants. I discovered that the unit will quit working if the base becomes overfilled with water; so, be careful not to jiggle it or it will burp and overfill. I also found that efficiency was lost after a while and, although I use distilled water, it helped to remove the lid on the base and wipe away the scuzzy film with q-tips. Later notes: I am now happily using three of these for my orchid plants. I've discovered the secret to getting excellent humidifying> As I put the 'plug' into the filled bottle I depress the plunger to release any internal pressure built up as I tighten the plug into place. Hope this makes sense because I am now getting great humidity for fussy orchid plants. Also, I use distilled water only and have to rarely clean scuzz from the devices.

I used these Last year to humidify my cheese refrigerator, worked great, the. Died after months of neglect. This year I bought two, one failed to,work at all. The other kinda worked if I fiddled with it. The vendor was great about sending a replacement. The replacement kinda worked, it would mist a bit, quit and then I’d fiddled with it and get it to run a bit. Now after a few weeks they just don ‘t work.I’ve cleaned the system and did everything possible, they just don’t work. Once a good product, now a waste of. Money. Find something else.

Do not buy this humidifier. I plugged it in and no mist came out. I gave it a little jiggle and it stopped working altogether. Tried emptying it and re-starting it but it still will not work. Did not even get a single use out of it.

I just got this today, but it is the last (I hope) in a long succession of misters. I make cheese, and part of the process is ripening the cheese in a temperature and humidity controlled environment. Well, I originally bought a simple mister; it turned off and on with a button. The problem, which I worked around by gluing the button down, was that when the humidity controller turned off, it shut off the mister, but when the controller would turn back on, the mister would stay off. And it was great, until the mister stopped working. So I ordered another one, which stopped working. So I ordered another one that I couldn't figure out how to make "always on". I think I've ordered and tried probably 10 different models over the last two years. Misters are so complicated now-lights, flashing lights, auto shut off after a period of time. It's almost impossible to find one that is just off or on. And then I found this one. NO BUTTON! A dial that will STAY ON. And it plugs into electric instead of a USB. Like I said, this is my first day with this and I hope it lasts at least a month or two, at least till my cheese ripens.
