Rated 3.6 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by Perfect fit All parts included except motor. Easy to install since we already had one. We replaced our 25 year old one. April 14, 2015
Rated 1.0 out of 5.0 by needed major repairs 2nd season in use Last year 6-15-12 I bought the master cool model ADA51. Had it installed by a licensed contractor, this year April 2013 went to start it up for spring, and discovered the wheel on the blower had come apart and was making a terrible noise. Essick Air, was quickly responsive to my request for warranty for the defective part, requiring submittal of documentation of the problem, and proof of purchase. I had excellent documentation thanks to my contractor; however the labor to replace the defective part was not covered under their warranty and I had to pay to have the defective part replaced. The cooler was purchased for my parents who are in their late 70’s, we selected the Master Cool because we thought it was a quality item and would only need routine maintenance for some years. However we incurred a substantial repair bill replacing the poorly welded squirrel cage not even 1 year after purchase needless to say I was highly disappointed and clearly made an error in assuming Master Cool was quality well made product.

Rated 5.0 out of 5.0 by A great look and real quite. The cooler was very easy to install. It is made better and has an extra lining for the water to sit in, so hopfully the bottom won't fall out like the last on did. The tumbler or bird cage seems more stout and sturdy. Less noise and the housing is easy on the eyes. May 20, 2014
Rated 5.0 out of 5.0 by Great! I was very skeptical of replacing my deteriorating unit with this unit. It was a hard decision to either replace or go with a central. Although the central is a better cooling system, the monthly bill is outrageous. With this unit, it cools my house enough (not as good a central) to be conformable. August 5, 2012
Rated 5.0 out of 5.0 by best very easy to use. i highly recommend this product. easy to install. love it May 21, 2014
Rated 2.0 out of 5.0 by Persevering with it. Shipping company lost the cooler for a couple days. It was bent up a little but straightened easily. Very little documentation. Store people didn't know much about it or how to get more information. Still don't know how to install it properly. Ordered a $180 1hp motor as it doesn't come with one. No pulley available from Home Depot. Very stinky even after running a month. A bit difficult all the way. August 5, 2014
Rated 4.0 out of 5.0 Awesome Cooler this really made our summer enjoyable, cool at night meant great sleep and during the day even with people over and in and out the house stayed very cool. August 23, 2009
Rated 2.0 out of 5.0 by Missing control logic and drain fitting This item is about twice as expensive as a standard evap cooler, yet it has some serious deficiencies. First, all the switching logic for the pump and hi/low speed must be supplied by the customer. I would have expected that the unit would have had a power input and hi/low/off input, with internal relays to complete the logic. Second, there is no connection/hole in the bottom of the wet unit to allow draining via external access, either manually at the unit or by a long tube with a valve at the bottom--you must gain access to the unit, remove the filter panel and filters, and then unplug the overflow tube. For a rooftop installation, this requires access to the unit. In Colorado, there are weather extremes that often result in a person turning on or off the heat/cooling systems, then a week later having to reverse the situation. This is not great for a rooftop unit that has to be accessed every time you begin filling it or draining it. July 16, 2014
