One star for being a decent heater and another star for the warranty. I mainly purchased this since I had the option to wall mount it and it was easy to transport with the wheels - plus I liked its minimal aesthetic. For the few months that it did work, the heater was quiet and warmed up my bedroom quickly. One day the heater just suddenly stopped working. I'm glad it came with a warranty and customer service was quick to send my replacement. However, my replacement heater stopped working even sooner at less than a month of usage. I contacted customer service again but they were unable to help the second time around. I'm really disappointed in the quality given the price point that it's at. I don't think I'll purchase anything from Newair again after my experience with this product.
