I had seen the Lasko space heater in both offices and homes for awhile and decided to get one for myself. Very efficient and quiet; except just a tiny bit noisy when first turned on— Until it heats up and gets going— Then it’s fairly quiet. Nothing to get excited or upset about though. I use it in a room with cathedral ceiling and it is very effective. I first run central heat for one cycle to heat room and then use Lasko to keep it warm rest of the time. IT WORKS!! If you are considering this, don’t hesitate; You will love it! Wish they made an ac for summer for same room!
