Bought a month ago and working great so far! It does make a consistent buzzing/humming noise when the cold water condenser is on, but it's similar to the noise a mini-fridge would make. I've turned the cold water condenser off for the winter (and left the hot water heater on), and I haven't noticed any noise since. The size is very compact and fits in my tight space perfectly, dispensing water is easy and convenient, and it fits a 3-gallon bottle (which is my preference) perfectly!
Trying another one since my wife likes the look. Last one died within a year but Avalon promptly replaced it under warranty so I will give it another chance. Worked great until then.
