I liked this product very much except that it did nothing for me. But I don't think it is the product's fault - I was just using it in too large a bedroom. It is well made, absolutely quiet, and does just what it says it will do. Might could work well in a small, closed bedroom. For me it went through about a half litre of water in about 10 hours.

I had my doubts on ordering this but i wanted something compact for work. My number one criteria being it had to be USB powered. This met and surpassed my expectations. It's easy to use and set up. Fill it with water click the ON button and a beautiful stream of mist rises from it. Press the button again and it goes into a intermittent mode. Misting on and off. In this mode a full "tank" of water would last an entire day. Adding to it's charm it has a nightlight. Long hold the power button and it flashes on. Hold it again and just like the mist, it goes into a slow flash mode. Time it just right and the light and mist look amazing. I would definitely recommend this to anyone looking for a desktop USB humidifier. Price, quality and function are all as expected.

I bought this a few months ago to keep on a table full of house plants that love humidity. It has been working reliably until recently. It now, despite a change of the small cylindrical filter and a good wipe down of the air outlet (it can get some dust in it so I thought maybe it was just clogged?), won't let off the steam even when it's turned on and filled with water. I'm not sure what happened, but I'm unfortunately now disappointed with the quality and longevity of this product. I will be reaching out to the company to ask for a replacement or suggestions for maintenance, which is a bummer after only a few months.

Though this item looks cute, it is not a quality product. It is so underpowered, it does not have the ability to even effect the humidity of a small closet. This little thing, even if it worked properly could never affect the moisture of an entire bedroom. No matter how small the bedroom. And in the case with this particular unit, water collects in the small hole that the vapor is supposed to emit, and it blocks the mist. So even if you have it set to continually emit, it becomes periodic and makes a hissing sound. It is powered by a USB cable with no wall attachment. So it is intended to be connected to a computer for constant power. Definitely returning this with no intention on a replacement of the same product.

I really like this small humidifier! I usually wake up with puffy eyes and snore overnight, as well as difficulty trying to fall asleep. I will say that when I use this and some lavender oils for aromatherapy, I fall asleep easier and don't snore overnight, and the best of all I don't wake up with puffy eyes. I have been using this every night for a couple months now and have to say it's worth the smaller size. I can use it when riding in the truck across country and sleep in the truck or camping somewhere with just a portable battery with no issues. You do have to fill it up each night, but if you just make that part of your nightly routine then it's not as much of a pain. Would recommend! I also haven't had a single issue with the filter falling off, with nightly use for over 3 months.

Not gonna lie. I don’t like being unable to purchase a replacement USB cable separately (I lost mine and ended up butchering a whole new device in order to get one). So now, instead of a backup cable I have a backup device. But I love how portable, how quiet, easy to clean, and lightweight, how compact, and how effective this humidifier is. NO MORE SINUS INFECTIONS from dry winter air. Not even keeping my large, noisy, hard-to-refill-and-lug-around humidifiers anymore. THIS is the way to go.

It specifically states plug 5v cable for charging. There is no “Charging” going on by any real definition of the word. There isn’t any batteries or capacitors to store electricity for future use of any kind, no 18650s no cheap rechargeable batteries, nothing. I looked! This humidifier does not, and will not, function without being plugged into the wall -That btw, doesn’t come with the power box to plug into the wall, only their 5v “Charging” cable. I was surprised to find, although to late for me, several others have already mentioned this in their posts as well but the misleading picture of it being held (while working and emitting steam) without any visible wires or being plugged in and the words “charging” cable and “portable” are still in the product description. This leads me to believe the wording and image’s are left in the product description to specifically mislead consumers. If this isn’t bad enough, I’ve had this humidifier 2 days now and it’s only been plugged in for 1 and already it’s acting crazy. It turns on for a minute or two and then shuts off permanently. When I try to turn it back on the lights flash four times and then nothing, I push the button again this time I only get a little half blink of the light and no steam. Not a good start. Granted, it’s clearly a cheapo product but I expected a little better than this. I’m returning this item and would recommend that anyone else thinking of purchasing this stop and get something else. TLDNR: It’s NOT Charge/rechargeable, it’s portable only in the sense that you can pick it up after unplugging it from the wall. It’s a cheapo crapshoot between 1 day or 10.

This little guy runs all night on continuously. It’ll run 15 hours on the intermittent setting. No noise. So easy operation! Great vapor. I’ve never owned a humidifier as helpful as this one! My sinuses are clear every morning. I set it right next to my head and breathe fresh air even while heating with a space heater. Space heaters dry the air out, terribly. This is a good deal and it actually works. I’m using it now! It has a usb connection and an adjustable night light. Good product! I’d say it’s a 10 STAR ⭐️ I bought two. One for my wife and she was so happy about it!!
