This is an air cooler. It has been used for only two years. It runs on water, meaning you need to pour at least 10 to 15 liters of water inside before running it to get cool air. It is completely imported from China and brought by hand. There is no risk of it breaking, and it is a very sturdy electronic device. Everything is in perfect working order, including the switches and the fan. You can buy it with confidence. Thank you.
