THREE Years and still running!
JAN 2015: Works perfectly! We've set ours at about half for several nights, all night long and the tank was still 1/4 to 1/2 full. We ran it on full blast for 7 hours at one point, and there was still at least 1/4 tank left. It makes a quiet hum, but doesn't affect your sleep.It's a nice compact size, but not tiny. You can see the steam that comes out- we like that. If you set it on a carpet floor, the carpet will be slightly damp there after awhile. Not damaging, but even setting it on a stool corrects that if it bothers you. And make sure it's not pointed directly at something, as that object will end up quite damp. For $27 and no filters, ya can't beat it!UPDATE JANUARY 2017:2 years and still going! I'm amazed. After about a year, it would make this awful noise when you first turned it on and sometimes it wouldn't come on. I thought it was broken, but we just left it on and in a minute or two it kicked on. The awful noise would disappear after about 20 seconds. It still does that sometimes. We do not clean it either- we use it all winter, store it all summer-- no filters to deal with. I am really impressed with this little guy!UPDATE JANUARY 2018:Still going strong! Love this little guy. Just yesterday soaked it in white vinegar for the day, rinsed and scrubbed the hard water deposits (I've done this maybe 3 times total in the last 3 years) It hasn't made the loud noise for about 9 months - no filter, no problem - absolutely love it!

Works well, output adjusts well, and very quiet. Seems like good quality.
This thing really puts out a good blast when on full. I usually turn it down after a few minutes. Not made for a whole house, but does well for a room at a time, or a section of a big room.Easy to use, easy to fill.Compact and looks nice. Some have bigger tanks but this one is good enough for 5 to 10 hours depending on how high you adjust the output. We usually only run it for 2 or 3.Very satisfied !

***UPDATE*** BUY SOMETHING ELSE!
The media could not be loaded. ***UPDATE*** As of November 2019 - I hearby edit my previous review. THIS HUMIDIFIER SUCKS! It is NOT consistent in it's humidifying. I can fill it and turn it on full blast (yes- making sure it's seated properly, etc) and some nights it will barely change level, some nights it uses the whole tank. I have done everything you are supposed to do. I use distilled water, I clean it every month, I make sure it's dry before putting away for the season. It's not even a year old as I only bought it early this year. Bottom line, don't bother with this humidifier. I have a Homedics brand I got from Costco a few years back that is still going strong, consistent etc. Honeywell is no longer the brand it was known for quality. Very crappy humidifier.********This is a very basic humidifier. I bought it for an appropriate sized room. It had no problem humidifying the area. I had no issues setting it up. It is small. I use strictly distilled water and do not expect any issues with cleaning it weekly or as needed.The only issue is the sound. I'm not talking about the low hum or dull low whine that most humidifiers make. This is a constant trickle sound. Kinda like when you get a large snow and the day it melts off your roof, you hear the liquid trickling down your gutters all day and all night, THAT sound. I assumed it would stop when it filled up the lower chamber. But no. I guess it's no more annoying than a zen fountain. I just wasn't expecting it. Maybe some people call it white noise. It won't be used in my bedroom, that's for sure.It doesn't just happen at "full speed". It makes the noise at any point on the knob. I'll try to submit a video.It does do what it's supposed to do.

Quiet, efficient, perfect size
Yet another great quiet product from Honeywell! I love their quiet tower fans, and now I love this little humidifier. It's small enough to fit on a shelf in my bedroom, it puts out a very fine cool mist that doesn't damage the wall or other surfaces, it's easy to fill and clean, has a wide range of settings, and really does the job, all for a reasonable price. And did I mention, it's QUIET? (I'm highly sensitive to electrical noise, so this is a top priority for me.) In a 10x12 room, it took less than a couple of hours to go from 30% humidity to a much more comfortable 55-60%. No more dry sinuses, and no more static shocks to my cats, so win-win. It also shuts off automatically when it's empty, and there's a spot for putting essential oils (although it is NOT a diffuser).I highly recommend this humidifier for anyone who has a small space with low humidity issues.

but I was in high need of an affordable and good size humidifier
Some of the reviews made me nervous, but I was in high need of an affordable and good size humidifier. I have dry nose and throat during the night and disrupts my sleep, it can get so bad. What made this attractive was not only the size, price and brand name-Honeywell, but also that is does not require a filter. Major plus! I use distilled water and no build up has occurred within first 4 weeks of use. I will still do a cleaning as instructed with vinegar. The cool misty vapor is perfect and I have it by my bedside.The only con I can think of is that it does work best at its highest setting, but makes some burbly and gurgly sounds of the water. The sounds can be soothing but sometimes a big loud gurgle will wake me up, I guess I am considered a light sleeper. So I usually turn it at half way point on nob, and found it is a good compromise for sound while still getting a good amount of the vapor/ humidity. I will put it on max setting about 2 hours before bedtime with bedroom door closed, this helps a lot. I will also mention that this alone did not cure my dry nose. I also use coconut oil and find this with humidifier the perfect combo.Overall, for the price, effectiveness and low maintenance qualities, I gave this a 5 star rating.
