This air conditioner is very good. I've had it for three years, and it's never given me any problems. PROS: Good quality, cools very well, and has no problems of any kind. CONS: If you like a digital smart air conditioner, this one isn't for you since it's mechanical and doesn't have Wi-Fi. But you can add a smart plug and manually set it to the setting you want, and it works perfectly. That's how I use it. It's for small spaces, for example, a room with a queen or full bed.
