    The price was great for the item but takes too much energy and needs a different type of plug outlet.

    This is purchased to fulfill the two purposes cold and heat. But as soon as we entered in winter season we turned on the heat and guess what it is not giving any heat and we have to put a separate heater in the room. The description says it will give the heat but in reality, it does not give any heat. I would not buy this again.
