The point is if using it in an enclosed environment the cooling is offset by the raised humidity, which counters your body's ability to cool itself.
Evaporative coolers in an enclosed environment do nothing more than laying out a bunch of cups filled with water on the floor and running a fan over them. Doing this to cool your house is a bad idea unless you ALSO need to raise your humidity levels for health and comfort.
In an extremely dry environment indoors, or pretty much whatever outdoors since you can't raise the humidity any more than it already is, it can make sense.
for the people saying it won't work in humid environments, have you ever used one like this that you add ice cubes to?
there is no way this is normally $259 lol, its basically a fan with a few ice cube/water trays.
Since this is a 3rd party seller it only has a 30 day return window, but it can be returned to any walmart store. I might take a chance and buy one to try it out, if it doesn't work very well, it will be an easy return for me.
As to the "ice", what you are talking about can be experienced by putting ice and a cloth behind a table fan. If anything those "Ice machine coolers" are making your house hotter by making the Ref work more to freeze more ice.
Evaporative coolers are awesome in Arizona. I will say on average it will cool the house 25-30 degrees from outside temperature. So it works well until about 100-105 I added one to my mom's house to help save her money on utilities and she loves it. Her Spring electric bills typically run around $140 and it dropped to $60. So that's a pretty huge difference and her house is much colder than she would keep it using the AC. She actually had to turn it off on occasion because it was too cold. Things she loves about it, colder air, costs almost nothing for electricity, fresh air in the house, and raises the humidity a little bit. Things she doesn't like is the seasonal maintenance and shut down. This is a real house unit, not one of these portables.
1. I provided more than opening a window and any intelligent person can see that.
2. Full house evaporative cooling works by opening windows. Evaporative cooling doesn't fail because a window is opened. You're thinking of AC.
You've convinced me you don't have a communication issue; you simply don't understand evaporative cooling.
My solution: Use a product like this and be comfortable for a minor increase in your electric bill.
Your solution: Don't use a cooling product. Just be uncomfortable and sweat.
Wow, why didn't I think of that? Why have AC or evaporative coolers at all? We can sweat! At least you allowed the person in your scenario to use a fan. You may be spiteful, but you're not a barbarian.

Theory is wrong if the real world disproves it. So let's stop talking theory and see what the real world looks like.
I live in a hot dry climate. I spent my youth living in houses cooled by full house evaporative coolers. We called them swamp coolers. They worked wonderfully.
Now I'm in a house with AC. The AC pulls what little precious humidity I have out of the air. To combat that, I run 3 humidifiers practically non-stop.
That's not unique. A LOT of people in hot dry climates use humidifiers to combat the dry air.
There you have it. Short and sweet. Your theory about adding water to the air being undesirable is poppycock. AC pulls humidity out of the air. There are people who live in dry climates.
You live in a humid climate? Yeah, don't use an evaporative cooler. No one is disputing that.
Drop the fantasy about a hermetically sealed room with eternally rising humidity. It's not realistic!
Evaporative coolers only work in the environments they're intended for? In your words "Um. Duh?"
The whole point I've been making is that these can work in the environment they're intended for.
But you've been stomping around saying evaporative coolers are bad because they reduce your body's ability to perform its own evaporative cooling through sweat.
If you reduce the ambient temperature with an evaporative cooler, you don't NEED to sweat. Or even if you still do, an evaporative cooler provides greater cooling than the decrease in sweat effectiveness caused by the raise in humidity.
In other words, sweating alone will keep you hotter than running air through an evaporative cooler and then sweating. Why you continually suggest sweating is a better alternative to being at a comfortable temperature I'll never understand.

I'm arguing for one of two things. Both of which have a long history of being used successfully.
1. Use evaporative cooling with a window open. It works very well. Proper science and EXTENSIVE EMPIRICAL EVIDENCE support this.
2. Use local evaporative cooling with a window closed and an AC unit that removes excess humidity from the air.
I ignored your insanely wrong refrigerator example from before. But hey, you're still here so let's revisit it since it's a perfect example demonstrating that you don't understand the science involved at all. You said:
A unit like this is analogous to opening your refrigerator and feeling the cold air. It feels good in a very local space, but it overall HEATS your home.
But you're completely wrong about the evaporative cooler. I don't know how you could possibly believe you're correct unless "You are not getting this at all or understanding the science."
Generally speaking, an evaporative cooler will generate heat from the fan and the pump. But the heat generated is trivial compared to the cooling effect they produce. They don't heat a home. They cool it. No, it's not "magic" as you mocked. The trade off is that the humidity rises. So what do we do? IF THE HUMIDITY IS TOO HIGH, OPEN A WINDOW OR LET THE AC LOWER THE HUMIDITY.
You can mock the idea of opening a window, but once again, empirical evidence has shown this to be HIGHLY effective. So whatever big brain science you think you understand that says this won't work is wrong, which isn't surprising since you think running an evaporative cooler heats a room similar to opening a refrigerator door.

And yes, if you open your window to decrease the humidity, then you just also lost all the benefit from your cooling and all your energy was now wasted.
Everyone but you agrees these items units are a waste of energy and money. Everyone also agrees that in certain circumstances DIFFERENT evaporative coolers can be worth it, but it's rare and this unit isn't it. This is just a larger version of these:

And yes, they are outside, but indoor ones work too. At night you can open up all the doors and windows to get rid of the humidity if you think it's too high. Most drier climates get cool at night.
Once again, don't use appliances in an environment that they aren't intended for!

Second, that guy is in the Midwest in a COOL and HUMID environment!
His environment is the EXACT OPPOSITE of the one this is designed for!
80% RH outside, brought down to 50% RH inside by an AC.
The room is already at 67 degrees! He's wearing a jacket! I'd be too if my room was cooled to 67 degrees!
OF COURSE IT DOESN'T WORK WELL FOR HIM!
Third, he keep referring to it as a "personal AC", which obviously it isn't. It's a personal evaporative cooler. It should be marketed as such and compared as such.
Fourth, even he (in his cool, humid environment) says it would work in conjunction with AC to provide an additional personal temperature drop because the 3 degree drop it achieves for him is still noticeable.
Once again, use these in HOT and DRY climates!
I'm running 3 humidifiers and they can barely get my inside RH to 30%!
Do you understand how evaporative cooling gets better and better as RH gets lower and as ambient temperature rises? Lower RH and higher temperature both contribute to increased evaporation, which in turn results in a greater drop in temperature.

Side note, the instructions are awful and I still can't figure out what they are calling the "ice bin" without having to open the machine up. I just fill the resevior up with ice water and add a few cubes and it works.
