  • Vapor rather than mist

    Very little actual humidity added to the air. Can see vapor, but not feel anything. When turned to high setting worked at full speed only seconds. Runs at low speed regardless of setting.

  • Compact and Convenient

    This little humidifier works great for our bedroom and really helps with dry air at night. Its easy to fill, and takes little space on the dresser. The added surprise is the LIGHT SHOW which we were not expecting. Not sure if this is designed more for children, but we're dealing with it. Blues, greens, purples....alternating color and movement. We've referred other family members to Overstock and this product specifically.

  • rave lights

    I bought this humidifier for my bedroom and it is quiet but what I was not aware of from reading the description ahead of time was that it has this weird color changing LED light built in. The color cycles through green, blue, red and so forth and there is no way to disable the light, not that I can see; it's rather annoying and pretty bright. Fortunately, light doesn't disturb me much, but its so bright it could easily double as a night-light. I think had I known about this light before I probably would have kept looking for something else. The humidifier works just fine, be sure to adjust the setting because the first night we used it there was water puddling on the hardwood floors. Setting it to the lowest possible setting works well and doesn't result in sitting water. Overall I rate this product as average, it's not the worst and it's not the best.

  • Basic Humidifier with a "Plus"

    Humidifier was what I expected, basic turn knob control and directional spout. The visual appeal is what initially drew me to purchase the item. There was no mention of the LED light ‘feature” in the description. If mentioned, I most likely would have never purchased. Once turned on, the humidifier is illuminated by a ROYGIBV cycle of BRIGHT light. So bright that it keeps me awake at night. Works as intended, great design/ visual appeal, but due to the bright light illumination I scored a 3/5. If intended for a children’s room might be a good choice. If you need to sleep in blackout conditions as I do, do not purchase.

  • Excellent Customer Service

    I received my first humidifier quickly. I used it one night and when I filled it up the next night, the handle broke and the plastic cracked when it hit the floor. I had a huge mess, but mostly I was frustrated with myself. The instruction booklet advised to hold the water filled container from the bottom. It was my fault it was ruined. I called Overstock.com and asked if I could purchase a replacement part. The guy I spoke with told me that they did not sell replacement parts for this item. He suggested I contact the manufacturer. I attempted to do so, but was unable to reach anyone by phone at the number noted on line. The next day a very nice lady named Kristi called me and apologized for the lack of assistance I had gotten from their customer service department. Even though I told her that the ruined humidifier was my fault, she told me that they valued me as a customer (I shop at Overstock.com all the time) and she was expediting a brand new one to me. I got it in just a couple of days and am loving it. Unbelievable customer service! Kristi went over and beyond my expectations and I am very greatful! I recommend Overstock.com often and will certainly share this experience with others.

  • Positive Review

    I received this product in perfect condition. I love the fact that I am not having to fill it several times a day, like the other 2 humidifiers that I have, which is a Holmes and SunBeam. This product is great. I love the light colors at night changing from blue to green, it is very peaceful. Before I purchased this product there were some reviews that the lights were too bright at night. I find that this is not the case. I do not regret that I purchased this product and it was/is well worth the money. I plan on purchasing another one! Hope this review helps.
