The product arrived with a hole in the box and consequently a 3 inch diameter by 2 inch deep impression in the media. This is the reason for a one star deduction. It wasn't worth the time and effort to get an exchange. Note the word UNIVERSAL which means styrofoam filler(included) must be cut into strips to raise the media high enough for the water distribution housing to seat against the top and a one inch media strip(also included) to seal against the side. In an ideal world, this products media would exactly duplicate the original that came with the MasterCool cooler. This all said, this product does the job with a minimum of effort and I would purchase it again from Tractor Supply.

I ordered the product pictured, in the blue and brown box as shown. The published specs indicated a perfect fit for my particular MasterCool unit, an ADA71 model. The product shipped to me was something different, a "Munters CELdek" universal set of rigid pads intended a fit a large variety of rigid media evaporative coolers. As such, the package contained a variety of rigid media pads and a variety of different styrofoam pieces, which Munters says can be combined in various ways to fit different brands and models. I was able to put the pieces together in a manner that does fit my ADA71, leaving me with two extra, small, media pads, and two styrofoam pieces, I can't use. I could have bought the Munters product anywhere, but I wanted a truly fitted set of pads, as advertized by Tractor Supply, and I did not get the fitted set. Second, the Munters packaging said that the box includes two sets of water dispersion media, in different thicknesses, as needed to fit on top of the rigid media. In fact, no water dispersion media was included in the package, at all. I am disappointed.
