## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product!
*by C***W on February 8, 2016*

It was simple to install the filter and started working as soon as it was in water. It is silent and has a very light yellow and blue glow when running. This little thing put out plenty of mist but hasn't caused any dampness near the bowl it sits in. Turns of when it runs out of water. It is small, portable, plugs in to any usb port and very cute too. I bought it to use in the hotel when I travel to dry climates like Las Vegas or Denver. But I find myself using it at home during the cold dry weather. I'm going to buy an extra one now. Highly recommended!

### ⭐ Cute but doesn't work.
*by D***Y on June 24, 2016*

Works when it wants to and when it does it gets everything within 2 feet of it soaking wet. Frustrated because I travel a lot for work and it was the perfect size to pack along.

### ⭐⭐ Output is Sort of Okay, Controls Are An Exercise in Frustration
*by S***A on June 9, 2016*

The media could not be loaded. So I bought this hoping to supplement the humidifier we have in the bedroom at night. I get dried out a lot and have been a little sick as of late so I was hoping to add some humidity to the air around my desk.First off, it doesn’t float upright in the cup (or bowl as I tried at one point). It has terrible balance, which combined with the weight and stiffness of the cord, causes it to have an unsightly tilt and stick to the edge of the container. I can only imagine how much effort the stock photographer went through to get that perfectly-upright-in-the-middle photo in the description. I had difficulty just convincing it to keep the wick at the bottom fully submerged (massaging the cord to loosen it up a little helped a lot).It does output a moderately decent amount of mist for its size, but unless you’re sitting in a tiny space like a closet or have it blowing directly in your face, it’s not going to be noticeable. This will not change the humidity of a large space what-so-ever. I kind of knew that going in, but I was hoping it’d be at least a moderate localized effect (ie I just wanted to moisten the air between my chair and monitor since that’s where my face tends to float) but no such luck.The controls are a royal pain in the butt. In theory it’s supposed to be touch sensitive but in practice it’s extremely finicky (see video). It’s supposed to have two modes, one touch to set it to run for ~3 hours (yellow light displays) and a second touch to made it run for ~6 hours (blue light), with a third touch turning it off. About half the time it never registered a touch, and when it did it’s like the heavens had to align because the exact same spot, pressure, etc. won’t necessarily trigger it again. And good luck trying to turn it off, you’re better off just unplugging it than trying to tap it and have it stay off.In short, I was hopeful and eager for it to work out but it just doesn’t work well. Could be a fun toy for a kid maybe or for very specific circumstances (maybe someone desperate on a long flight?) but I doubt it’ll ever get much use for me again. Wasn’t worth the money.
