One of the over 17,600 users that gave the personal heater a five-star rating lives in Iowa and left a review remarking on the state’s “freezing cold winters.” Needing a little extra heat at night, the reviewer uses the heater to heat their whole room. The process takes about an hour, but once it’s warm, the heater has no problem “maintaining the warmth all night, even when temperatures get below zero.” The space heater comes in four options—black, white, blue, and pink. The wide array of colors helps the heater fit easily with many different styles of decor. Designed with safety in mind, the space heater has tip-over protection and stays cool to the touch.
