I have had this cooler for 3 summer's and replaced the pump 3 times. The pumps aren't cheap. I drain/clean the unit regularly. The cooler works great on the fan and controls. I really like the wireless control; I can turn it on before coming home and the patio will be cool. But I have to purchase another pump to replace the current one that isn't working before I can have it cooling with wet pads.
This Apex 2000 cooler cools down my shop very good on hot days, without this cooler it would be unbearable on very hot days. I highly recommend this cooler
