Review on Xdronray Portable Air Conditioner: Noiseless USB Desk Fan with 3 Speeds, LED Night, Office Cooler Humidifier & Purifier for Home Dorm Bedroom by Miguel Kriglstein

I'm a little surprised it has so many bad reviews. It's not perfect, but it certainly costs around $30. Here are some of my observations: Pros: - Blows cool air. That's probably why you're looking at it. It's not frigid air, but it's definitely chilly. - It rotates - It is easy to set up and fill with water. I didn't have a leak. Water lasts for a long time - The handle is comfortable - The design is very luxurious. I think it looks expensive. Cons: - With fan speed 1, spin and fog, it runs for about 3 hours with 100% battery. It takes less than 8 hours. It works when connected to the network. It's not air conditioning. This is a cold air blower. It blows a very, very light mist into the air to cool it down. It won't make your whole room cool. Think of it more as a cool fan. It blows cool air on you but doesn't lower the room temperature significantly. It makes a slight buzz that might bother someone. It's like a fan with a small motor. The higher the fan speed, the louder it gets. I think this is perfect for spaces like small rooms, cars, offices or bedrooms where you are trying to get some airflow. I am happy with my purchase so far. I will update if there are any changes.
