It's just a fan + heater. It's not an air conditioner, nor is it marketed as such.

I have one. It works pretty well. The air filter isn't as good as the massive Austin Air I use for my living room, but it's okay for a smaller room... not to mention much quieter, smaller, and easier to integrate with home automation.

Just like any fan, it makes you feel cooler. It doesn’t actually cool the air.
