Summary: Bought this for my cubicle because it's so, so dry in this office. It's not quiet (even on low), and needs refilling after maybe 4 hours (on low), but it's not a bad little machine. Never had a problem with leaks, super easy to fill, doesn't get scummy or moldy.
Summary: THIS IS MY SECOND ONE. THE FIRST LASTED NEAR 5 YEARS. I LOOKED ALL OVER FOR ANOTHER. IT WORKS SO WELL. DOES NOT LEAK OR MAKE MESSES. DOES NOT SPURT OUT ON STUFF. JUST FINE MIST. WORTH EVERY CENT.
Summary: The reservoir is indeed touchy & difficult to remove and re-install. I think this is the main cause of the frequent complaints of leaking. I've had mine in the office for a couple of years now. It never got too noisy (on low setting). I've always tried to clean it of scale & sediment.
Summary: Love it. Super quiet!! That's the one feature I was really looking for- quiet! Tank is probably smaller than you think- barely enough to last 8 hours, not really 10 hours. Night light is bright! I put tape over my night light it was so bright. But again - very quiet!!
Summary: I've tried several different humidifiers for my bedroom and this is the only one I can stand to leave on at night. It's sound is quiet enough for me to sleep and soothing. Some of the other ones I've bought make dripping noises that drive me crazy, this one doesn't do that.
Summary: I bought this unit about 2 years ago at Bed Bath & Beyond. I use it for my son's room. It has worked great, overall. The unit is one of the quietest humidifiers I've had yet. And it also works as a night light.
