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.
Humans cool by using evaporative cooling. So if the air is dry, simply moving it around gently (with a fan) will allow your built in evaporative cooling to work great. Any humidity you're adding to the air in any climate will simply reduce the effectiveness of your own evaporative cooling and ultimately make you feel warmer. If the climate is so extremely dry as to be causing problems already, sure, it doesn't hurt to add a bit of humidity to it even if you'll feel a bit warmer. But if your home's humidity is over 35-40% or so, you're just doing more harm than good.
Air conditioning works not only by cooling the air but just as importantly by drying it out. This is basically an anti-air conditioner.
Excerpts from a choice review:
"I bought this fan is placed in the dining room to use, choose their favorite white, received the goods very much like, the color makes people look very comfortable,"
and
"Touch screen design makes me feel very tech-struck. The design of the fan page makes families with small children safe and not afraid that children will cut their hands when they come across them."
Tech-struck? Fan page? .... the color makes people look very comfortable?
Further, as previously mentioned, they are mainly of a different unit entirely.
The stock photos even mention 'whole yard air circulation'.
One review mentions floating parts and not being able to reach the seller or manufacturer.
Not debating evaporative coolers (don't think they are much use to most people), but stay FAR FAR AWAY from this one.
I don't think people realize full house evaporative coolers as we know them have been in use for over 100 years. They were invented in Arizona, and everyone who's used one knows they work.
When it's painfully hot and a dry breeze hits you, it feels like being in a convection oven. But when the air is passed through an evaporative cooler, you immediately feel relief as the temperature comes down.
If you think science says evaporative coolers don't work, then you're making a mistake. Because repeatable empirical evidence disagrees with you. While you're at it, you might as well argue the world is flat. The amount of evidence and simple tests that prove you wrong is overwhelming.

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. If you're buying a refrigerator to cool your home, it won't work. But an AC unit works off the same principle but vents outside.
A whole house evaporative cooler would work very differently because the humidity would be vented outside like an AC and there would be an actual temperature drop with no added humidity.
As opposed to this unit, where venting it inside just makes the overall space worse, similar to the fridge example. There's no magic. It provides very local cooling (i.e., in front of the fan), by raising the humidity in the home itself, which unless you have very low humidity levels will just make you feel warmer because it counteracts your built in evaporative cooling system (sweating.) If you want to know what your home will feel like with un-vented evaporative cooling, fill your living room with small cups filled with water and turn on a fan. That's what this machine does. Nothing more.
If your home would benefit by having humidity anyway, then by all means, use one of these to do it with added benefits of having a cool breeze in front of it. But if not, don't.

1. Why do you think someone can't open a window when using this unit to vent excess humidity?
2. There is ABSOLUTELY an increase in indoor humidity when using a whole house evaporative cooler. Again, I don't know if you're suffering from a lack of understanding, or if you just struggle to communicate what you know. Since you took the time to explain obvious details regarding (essentially) closed systems and heat generation, I guess I'll also explain simple details that everyone already knows. Whole house evaporative coolers pull humidified air into the house. The air is exhausted out the windows due to positive pressure. The house becomes filled with cool humidified air. It's true that the humidity doesn't continue to rise after the air in the house has been fully replaced (maybe that's what you meant to say but didn't) but if you measure the humidity before and after using the evaporative cooler, it will absolutely have raised.
3. Because this isn't a whole house cooling solution, it's likely to be used to supplement existing whole house cooling. That whole house cooling is likely AC. When using this with AC in an already dry environment, the AC will have no problem removing the excess humidity generated by this unit.
For fun, let's examine another use for this with a scenario that I'm sure many can relate to. Let's say your kitchen has fine cooling, but you have a room that doesn't. This could be for a number of reasons. Far away from the AC blower, room over garage, corner room with highest sun exposure, poor insulation, whatever. Your humidity is low, and you use an air conditioner, which de-humidifies the house anyway, so raised humidity is beneficial, and comfortable humidity levels are unlikely to be exceeded. You can put ice cubes in this and cool the room suffering from sub-optimal cooling to make it more pleasant. In this scenario, we'll say you don't want to open your windows because California is on fire and turning the outside air into a cloud of death. The freezer will have to work harder to produce the ice cubes. In turn, the AC will have to work harder to compensate for the freezer. The user will have to decide if this is a good solution. But I don't think the answer is cut and dried.

That's literally how evaporative coolers work. It's even in the name. They often drop the temperature so much that the human body doesn't need to use its own evaporative cooling. It's not just about "feeling" cooler. It's about actually a measurable drop in temperature.
Three huge problems with that.
1. Why do you think someone can't open a window when using this unit to vent excess humidity?
2. There is ABSOLUTELY an increase in indoor humidity when using a whole house evaporative cooler.

Well darn, I thought there was magic involved. If you want to drop the humidity, open a window or let the AC pull it out. Does that count as magic?
Ooh, bold. It does exactly the same thing that a whole house evaporative cooler does, minus the forced air intake. In both cases you can vent by opening a window. If the humidity rises too high, you can position it by a window pulling air in, or use a fan to create positive pressure.

But I don't think the answer is cut and dried.
And in your specialized scenario, the obvious solution is to run a fan and use your body's evaporative cooling. Which will function great as long as you don't raise the humidity in the space...
