This review has to deal more with the condition of the unit received than its performance. I purchased this unit earlier this month (4/2021) and I was really hoping it would help cool down my attic, but I was shock to see the condition of the item sent to which was purchased as a “new item”. I know items can get damaged in transportation but this item was clearly used and damaged and still sent to me. There were items missing in the box as well. As an BB Elite Plus member I was very disappointed to receive this item in this condition since it was sold to me as a new item. All I received from Best Buy was an apology but I felt like more could have been done to compensate for having to return this item that is pretty heavy. They never even ask to see how the item was received. Most companies offer a discount on your next purchase. Hopefully someone at BB will receive this and do a little more.

My only complaint is that the remote & control panel are inconsistent. When I set the temp from the remote then try to change the temp on the panel, the system won't recognize it initially. I have to change it again on the panel - almost to reset the capability... and vice versa. This winter, I almost forgot about the heating feature and would have had to spend $200 or $300 for a new heater to heat the attic. I double checked the manual and it was running in no time.

Very easy to assemble, easy to use. Many people complained about the noise level, it is not extremely loud. Looking forward to testing the heat function in the winter.
