Presentation of this air conditioner is nice but it’s not as good an AC as I wanted or expected it to be. It doesn’t cool my bedroom unless it’s on the highest setting. So no need for me to have any other speed, modes, or numbers besides 64, high, cool (ha ha!) they serve no purpose. I’ve even taken adequate measures to ensure that the way I installed it wasn’t the problem and it isn’t :). Next time I won’t get sold by the cost of a something. My advice is for people go invest in to something as crucial as an air conditioner, for summers such as this one.
