These are awesome! I put it in my bedroom where the air flow is lacking. It was a game changer. I actually purchased 2, the second one was for my main room just because it’s a huge area. One downside—-The one in my bedroom has to be unplugged to be cut off, the buttons do not cut it off. The one in my main room can just be turned off by the buttons. I just unplug the one in my bedroom in the mornings & use it to keep my room comfy at night. At the price they are they should function 100%. They aren’t super noisy and they fit well. They install easily.
