    Energy bill barely moved after installing this. Was expecting a big spike but the energy-saving mode really works.

    Dehumidifier mode is underrated. Super humid summers here and this thing makes the room feel 10 degrees cooler just from pulling the moisture out.

    Works like a dream and was pretty easy to install. Cools my entire 1-bedroom apartment. Best thing is I can leave it in year round because it is out of the way.

    The U-shape design is a game changer. My window stays open, fresh air comes in, and the room is still freezing cold. Never going back to a regular window unit.
