Hessaire MC61M Indoor/Outdoor Portable 1,600 Sq Ft Evaporative Swamp Air Cooler

I read other reviews on Walmart's and Home Depot's web site and took the plunge to buy this unit through Walmart. One of the best choices ever. Have used it both indoors and outdoors in the Phoenix area...this weekend (June 4) it got up to a new record of about 116. Used it outside and dropped the patio temp from about 110 to 89 later in the evening (yes, it was still 110 around 6 PM). Granted, our patio is enclosed with two sides open and have a roll down shade awning on part of one side that's open. The evaporator sits on the patio pavers pointed to the patio part where we sit, so the cool air from the evaporator gets blown into that area. It's kind of a 2 1/2 sided enclosed outdoor room that holds in some of the cool air. Assembly was pretty easy. The casters are heavy duty and the machine is easy to roll around. When assembling, the casters are inside the back of the machine, so you need to unscrew the back panel to get at the box containing the casters. Because of reading another review, that's how I knew. Otherwise I would maybe have thought the casters are missing. Hessaire should place a label on the cabinet saying you need to take off the back panel to get the casters. Using the machine inside has also worked well. It sits inside the front door and blows out the back door. It's a distance of about 40 feet with a couple hallways and bedrooms off of the main air flow (probably about 1600 sq ft for all of that area) and it still cools down about 10 degrees. In the end, very satisfied with the machine and would buy another. Got Walmart's extended warranty plan just in case, because during the months of mid-May to mid-October is will be used constantly either indoors or out. Indoors, we'll use A/C on the hottest days (like 105+ degrees) and use the evaporator on the patio. Less than 105, we'll use the evap indoors during the day and possibly move it outside later in the day. It's really that easy to move.
