Review Content Great personal humidifier! Have used every night since purchace. Quiet operation and a normal bottle set on a lower setting lasts all night long. Remember to take the collar ring off the bottle for a great fit and no leaks. If you travel alot, must have for those dry hotel rooms. Could see a lower price, but nothing its size available comparable. About the size of 2 bars of soap stacked with 3 adapters. Overall a very good buy. Plus, has soothing blue night light in operation. Easy Breathing in the Mile High City I live in Los Angeles and recently had to fly to Denver to do business. The altitude and dry air always made for an uncomfortable sleep. This trip I used the portable humidifier and slept great. Its portable and light weight and has a nice blue night light too. Great Product! I travel enough during the year that this is excellent for those dry hotel rooms. Perfect for travel Works great for hotel stays, helps me breath easier at night Nice I purchased this as my husband and I were going to be traveling to the southwest and always have issues with the dry air in hotels, this item was easily packed in our suitcase and a bottle lasted all night. A must have if you travel This is a really good humidifier. It actually puts out a significant amount of water vapor. The light is a bit bright for my liking, but do not let that sway you. Perfect for travel. Super compact and super light.
