  • Not great quality but does the job
**Update*** I am impressed with their customer service. After I left 2 star review, they contacted me by themselves and made it right. I am happy! **Old Review** The Patio Swamp Cooler, designed to offer relief during hot, dry summer months, initially seems like a promising solution for outdoor cooling needs. With its user-friendly controls and robust build, one might expect this to be a winner. However, the unit disappointingly fails to fully deliver on several counts. The cooling capacity of the unit is commendable. It manages to lower the temperature significantly in an outdoor setting, adding comfort to any patio area. This is particularly impressive given that swamp coolers, unlike traditional air conditioners, can struggle with outdoor use. This cooler's ability to create a comfortable microclimate even in the face of scorching heat is its greatest strength. Unfortunately, the promising performance is let down by various design flaws. First, the ice packs, which are meant to enhance the cooler's efficiency, have a tendency to leak. This not only leads to water waste but also potentially damps the surrounding area, posing a slipping hazard. Secondly, there's an issue with the orientation of the front blades. Instead of holding a straight alignment for optimal airflow, they sag downwards. This flaw drastically hinders the cooler's ability to distribute air evenly, affecting the overall cooling experience. I found a workaround by wedging a piece of wood between the blades, but it's a nuisance to do and something you shouldn't need to rig in a well-designed product. Lastly, the most glaring issue is the faulty water mechanism, which is meant to automatically cut off water supply once the base reservoir is full. Sadly, it doesn't seem to function as intended, leading to water overflowing. This necessitates constant monitoring and manual intervention, diminishing the convenience factor of the product. In summary, while the Patio Swamp Cooler does offer substantial cooling capacity, the presence of design flaws - leaky ice packs, downward-sagging front blades, and a non-functioning water cut-off mechanism - all result in a product that fails to live up to expectations. Its significant cooling ability is overshadowed by the inconveniences and hazards posed by its design shortcomings. Unfortunately, until these issues are rectified, it's difficult to give this product a higher rating. ... show more

  • This cooler is amazing!!
I've bought that cooler for my backyard and garage. It really works and gets the temperature down quite a bit. I am living in a really, really dry region, though. So I can't say if it works in a humid area. I think probably not that good. But anyhow, it does the job for me. The option that you can add ice to the top is making a huge difference! We put icepacks in there (3 were included!!!) and when they are done, we swap with others or even just put a bag of ice on top. It cooled down AT LEAST 20 degrees! Love that thing! Downside is: The water compartment at the bottom is not sealed. So when you move it while it is full, you will spill water everywhere. Therefore 4 stars, not 5. But other than that: I recommend!!! (Oh, the sticker on top came off after operating it outside, but that was also in 110 degrees weather, so meh, doesn't really bother me.) ... show more

  • A must have for the Summer.
I live in Florida and it gets SO extremely hot. I have cats that love to sit out on the screened in porch but normal fans are not enough and the ceiling fan is not enough to keep them cool. So I bought this for the front porch. It is HUGE. And I thought because of this it would be really loud and scare my cats but to my surprise it's not. It puts out A LOT of air. And so far I've just used the regular fan function and not the cooling part. I will try that this afternoon when it gets really hot. But the fan ALONE makes a HUGE difference in the tempature. And the swing feature keeps the air flowing and covers the entire screened lanai. I am so glad I bought this. To be honest I kind of thought it was a scam like how is ice and water going to make that much of a difference? The ice will melt in 5 seconds here in Fl. But like I said I haven't even used the cooling function yet and the fan alone is worth the money. I can see why they say it's industrial strength not because it's so big but it really puts out a lot of air. And makes a HUGE difference in the temperature here in Florida. I LOVE it!!! And my cats love it. They can sit out on their porch and be comfortable. And I don't have to worry about them getting to hot. It gives peace of mind. Don't hesitate to buy this. It's NOT a scam. UPDATE: July 5, 2023 yesterday I tried the cooling feature. I use cold ice water from the fridge when I add water and I bought extra ice packs because there so small. And I change them out regularly. I've also filled zip lock bags full of ice. So I can keep adding ice like every 2 hours. That sounds like a lot aggravation to stay cool but the feel like temp yesterday was 100 here in Fl. So in weather like this if you want to feel a cool breeze keep adding ice water and or ice. As I mentioned I got this for my cats so they can sit on the porch but at any time they can come in and go out. However even with this and it does cool things off but with feel like temp getting to 100 I bring them inside and close the porch door so they can't go out. Even if it cools the temp down by 10 degrees or so? 90 is still to hot for ANY fur baby to be outside. This is extreme weather we have in Fl. in the summer months. So if you live in other states this will work even better for you. I LOVE this and I am so glad I got it. I am Very pleased. And my cats are pleased. ... show more

  • Back won't come off? Solution found.
This machine has a quiet fan that puts out lots of air. It seems to be well made. Unfortunately, the back would not not come off of our machine so that it could be maintained. I requested the removal instructions from the vendor and found my cooler was defective. Removing the 6 clips, the back would not slip up and out like it is supposed to. The problem is the pad is thick and won't move up into a cavity that would allow the door to open. The solution is to pull back on the vents at the top of the door as you push the door up. You might have to have someone hold the machine as you pull and slide up. ... show more
