Title: Fine on the 2nd Try
Review: The first unit I received did not work. Amazon quickly and painlessly replaced it, and the 2nd unit is working fine.I keep it in an unfinished part of the basement, and it works very well. The noise is audible in the finished portion of the basement, but it's not a big deal (there's also a vented water heater and HVAC making even more noise).Note that if you want the unit to drain continuously (vs. filling a reservoir that you need to empty manually), then you need to be able to drill a small hole in the bottom of the reservoir. It's not hard, but you will need a drill and bit. The unit comes with a rubber stopper to plug this hole in case you want to use the reservoir later.
