Just bought and installed this AC for our small bedroom. It's a nice size as to where a person could easily install it on their own. Not very heavy. We've had Haier window units before and have always liked them. This one is simpler model than ones we've had before. With this model you have two rotary dials. The top one is the thermostat with settings 1 thru 10, 1 being minimum cool and 10 being maximum cool. Does not give you actual temperature. The second dial is how you turn on the unit, choosing either low fan, high fan, low cool or high cool. Super simple and easy to use and cools our 10x10ft room nicely. A few thing I miss from previous models is having a remote, a digital temp display, and being able to angle fins up and down (you are able to angle side to side).
