It's very very very good product... The size is perfect, for a person which travels every week like me.. And very good inside airplane.... I Recommend.

Three of us at work have it and it's been working great. We all use it non-stop Monday-Friday, running it straight for 8 hours a day at our desks. I'm not sure what happened to the personal humidifiers that have negative ratings but out of the 3 of us, all of them work great. A few things that helped was that in the beginning I felt that my humidifier wasn't blowing as much as my coworker's but one day I switched out the Costco water bottle for a slightly larger Dasani water bottle and somehow that seemed to do the trick. For people that run into the problem of no mist when the machine is on, you just have to adjust the top part of the device a little until the mist is able to blow out. I just played with it tilting it and such and found that after you tilt it a little and set it down lightly, it should work fine if it stops spitting out. Sometimes when too much water leaks into the machine at once, the mist blowing is off also. If that happens you should pour out the water from the machine and then attach the water bottle back into the machine at a 90 degree angle. Overall I'm so glad I got this product. I'm actually planning to buy another one for my home.

I travel frequently and, while working on a job, my old travel humidifier kicked the bucket. After much internet searching, I found this nifty little device. First off, it's MUCH smaller than you think-- slightly larger than a large box of 250-ct matches. Insert a water bottle, plug it in & you're set. Easy to clean & carry with you, the thing I love most about it is that if it runs out of water, it stops on it's own. It puts out a large amount of cold humid air for it's stature, but unfortunately it struggled against the incredibly dry air in the Minneapolis hotel room where I was staying. My recommendation would be to run the humidifier all day while you're gone with the door closed to your room and see if that humidifies the space more effectively.
