Received this unit as a warranty replacement for an earlier model purchased in 2018 and am very happy with the replacement. Unit has been working great to keep humidity down in my 800 sqft basement. I have unit set to 50%, it cycles on/off throughout the day, and humidity meter across the room measures 45-55%. Pump system is fantastic works well with small tubing provided with unit. Love that this is a set it and forget it system. Only downside after 1 month of use is that the unit generates quite a bit of heat. Prior to plugging in, my basement had been a consistent 72F and within 2-3 days of use, basement temps were up to 78F and have stayed that high since.
