I got this TRD40615E De'Longhi Dragon Digital Full Room Radiant Heater.Well i'm giving it 4 because it took two days to really heat my room. To its defents I have a really big bed room and it does not have a heater duct. I want to say it has really cool features. I love that it has a timer and it doesn't over heat the room. I do not like that it doesn't have a fan to blow the heat around. But other than that I really do love the the heat its throwing out.
