I truly don’t understand the poor reviews. People need to read and follow the directions. I now have four and they have been awesome. Mine are not in the wall but on the floor. Always remember the first temp is the actual vent temp of what is coming from A/C or Furnace. It is Not the temp of the room. You whole house Thermostat is that control. The second is what you set the unit to stop the forceful blower to disengage. The third is for what is off and fourth is the blower speed of the small unit. Always remember to go back to the number one (vent temp) so the light will turn off in five minutes. Otherwise it will stay on. These little fan vents work awesome win the upstairs of my house where certain rooms are always too hot or too cold. Especially my walk in closet. I won’t have to have a small heater in there anymore. Even if they only last a year or two- who cares? These are little fans that run a lot. By the units when they are on sale. I already bought two more as backups. At night set the fan to 6- then it’s not loud. I put it to ten during the day with 90 degree days. I have four and not an issue with the remotes.
