I have had this heater for a few weeks now and so far it is working better than the one I was using. My bedroom is the coldest room, it has zero insulation and I spend a lot on heating in the winter for a small apartment. This year I put down carpeting and got a bigger heater (this heater) and the difference is amazing so far. We had a cold week and it kept the room toasty. Until this heater, the best heater I have owned was a tabletop infrared I picked up on sale Black Friday two years ago. I also have a ceramic which works well too. This unit shuts off when it hits the temp you set it at, it also has low and high, I have been running on low at 68. We will see when the bill comes how it faired. I will update the review. Normally I need to run two heaters, one at each end of the apartment and the radiator in the middle on low, with this I have only used the radiator on low and my apartment is warm. I also move the dryer vent inside in the winter, why waste heat? I really hope it saves me some money along with the carpets I put down. This unit is much larger than I expected, very solid, it wheels easily which is why I chose it. It also has a safety feature for tip over but I could not see this being tipped over unless you gave it a hard kick and even then I doubt it would go. This is a very nice heater, nothing about it feels cheap. I leave them running when I am not home, I lower the heat when we are not there. I feel completely safe to do it. If you are looking for a heater that is well built and can heat a large room, maybe even my whole apartment if I placed it in the middle, this is a great unit. Also the 1st time I ran I did have a slight smell but I expect this and it did not last long.
