Champion cooler 4700 model
Product works great air outflow is is real good so is the water output for cooling. Some of the screws at the top of the watering pan leak because they weren't fitted with felt washers. Used silicone around the screws to prevent leaking. I had a Champion evaporator cooler for many many years and it worked great. I noticed the metal isn't as heavy gauge on the new model though. However, I hope to get many years of good use out of this one. Also appreciate the remote control option.

Super impressed
I live in the desert of California. This is a blessing. No more high electrical bills during the summer. It cooled my house from 83 to 71 in about an hour. The air is crisp and clean. I highly recommend this cooler. You’ll need a second set of hands for the install.

    Cheap and Shoddy PART 2
    This is Part 2 of my previous review titled Cheap and Shoddy, including the photos. (Apparently you can’t modify a review once it’s published on the HD site.) This second time, the oil had gotten slung all over, compliments of the belt wheel. It was all over the inside of the case and in the water. I wiped it all off and drained the water so that the oil wouldn’t go through the pump and into the cooling pads, when I noticed that the belt was also a little loose. Loosening the adjustment bolts, I noticed that one bolt was completely missing! It had obviously never been installed! Now, weeks later, I opened the unit up for another inspection/flush. (It seemed to be blowing at a much lower volume as well.) I still needed to use a screwdriver to remove all the panels because they’re so tight in the frame that I can’t open it by using the built-in handle without bending it (it’s made of flimsy thin metal). I also noticed this time the presence of sand in the water, which obviously got in through the large 1/4” gap at the bottom of this panel. And once again there was oil slung all over, including on the inside of the belt, which was loose and covered in what looked like soot (from the oil no doubt). The same oily soot was not only all over the fan fins and exit vent but had created a fine film all over the room inside! I spent hours cleaning the room and carpet in the next hallway, all resulting from over oiling the fan axle!

      Firstly, once we got this cooler installed, it works great. However, there is a lot to be said about quality control for craftsmanship. We knew from the start that we would need to convert the tunnel to a vertical orientation rather than the factory horizontal position. We also knew that the cooler did not come with the panels needed for the conversion.and it required that we call the manufacturer to get the parts. It took five days for the parts to arrive. Our question is why doesn't Champion have these parts at Home Depot for customers who need them instead of making the purchaser wait for the parts before the cooler can be installed and used? Secondly, once we opened the packaging, we found a bolt missing for the motor mounting bracket. Rather than calling Champion, we went to the hardware store for the correct bolt and installed it ourselves. Although a simple fix, we expect that all necessary hardware be installed at the factory. Perhaps we are asking too much - what should we expect after paying $700 for the cooler... Thirdly, the unit had a dent in the top of the frame that prevented one of the pad holders from being removed. We had to tap the dent out from the inside in order to remove the pad holder. Lastly (AND MOST IMPORTANTLY), once the cooler was installed and we began filling the pan, water was leaking from the corner of the pan. Upon inspection, there was a 1" stretch tear in the metal (obviously from the manufacturing process). This was not a result of shipping damage - this was a manufacturing defect. Rather than uninstalling the entire unit and returning it to Home Depot, we drained the pan and used epoxy on the inside and outside of the crack to seal the defect. After all of this, we were able to finally use the cooler. If you buy this product, be sure to strip the packaging at Home Depot and give it a close inspection BEFORE you buy it. If you enjoy having to make repairs to a brand new cooler, then just cart it on home and take your chances.

      debincolorado, Thank you for taking the time to review our cooler. I apologize for the inconvenience you've experienced. The motor mount bracket on this unit is designed to only have one bolt, it's all that's needed. I will pass on your suggestion to have a few conversions strips available at the stores to be given out at time of purchase. If you took a picture of the 1" tear in the bottom pan, I would really like to see it. This would be great to send to our manufacturing team to prevent this from happening in the future. I would also like to request that you contact our customer service team for anything missing, damages, or defects. This will give us the opportunity to fix or replace under warranty at no charge. Thank you, Tina / Champion Cooler

      We bought this cooler for our 2 story cabin one hour north of Seattle. The cabin got very stuffy and hot due to the metal roof and not great ventilation. The cabin also is a vacation rental. 2 heT pump units were near 10 grand and we were concerned with elect bills and recycling air/odors. The swamp cooler was installed just above the floor on the first level. We open the upstairs window and in 5 minutes the air has been freshened and the cabin cooled up and down by about 10 degrees. 70 percent humidity is the highest we have seen inside. That is back below 50 percent the next morning. This is just for the 8 weeks a year it gets over 80 here. Fan runs quiet on low and is not bad on high. The moisture inside really helps. No mold issues. Overall a great 20th century product that should last with our limited use.

      I only gave it 4 stars because it doesn't cool the entire house down. That could be because of the floorplan. I purchased this as a temporary way to cool the area down, which it does. It will work great in my garage. Called Customer service and and they were great. I had the part needed to do a horizontal mount shipped to me at no cost!

      Awesome cooler for the money. Cools off front of my house and I have another 1 that cools off the back of the house. Total is 10000 CFM .. I like to cool in the summer. Super quiet and the remote works on both of the coolers.

        Performed as expected.
        We live in western Washington where evaporative coolers are not normally used. The summers here normally have middle level humidity, but this summer has been unusually dry. I decided to try an evaporative cooler and have not been disappointed. It cools the house 10 to 15 degrees cooler than without the cooler. It had been 90° in the house at the end of the day, now it is anywhere from 68 to 78 depending on the outside temperature. The quality seems okay for an evaporative cooler, which is basically a water pump and an air pump inside a large metal box.

        Cools nicely
        Admittedly, it's only been installed a day, but wow did it make a difference in my parents' 1,400 sf house in just minutes. Mounted it in the window at the end of the hall and it blows all the way down and into the living room. Open the front door a crack on the other side of the house and you feel a nice gentle cool breeze. Runs very quietly too. The old unit was also a Champion and it lasted around 20 years. I wasn't comfortable with the thin chains and mounting hardware so had a platform built instead. Float assembly didn't look too durable but it works.
