This is a great product because it works so well and it has the best features on it. The timer is so accurate and easy to set as long as you read the directions. The directions for use are easy to follow. It suppose to heat a big room but it heats a whole floor and I don’t have a really huge house but it’s a big house and the heater heats my whole upstairs on medium I haven’t had to use the high setting yet because it works that good. I would definitely recommend this heater especially if you’re wanting to heat a small apartment or just a room because you’ll have a comfortable warmth.
