I have owned many LG portable A/C models. Overall I like LG. The LP0721 model overall is nice. I like the dimming light feature and mine blows very cold air which is great.. The main thing is that almost no matter what temperature I set it at it cools way below. I can set it at 76F and it will cool down to 68F.  But also I can set it to 77F and it could be from 68-77F.. The room is only like 250 square feet.  I have never had this issue with any other model.. I am not sure if maybe the thermostat on the A/C isn't sensing the temperature, but them sometimes it seems like it does. I have reset it, I have move location on it.. same thing happens.. I have different thermometers to confirm and its like the temperature is random, but always low.. which is better than it not working for sure... But I use it in my kids room and I dont want it super cold in there. I may have to buy another model.
