This little electric heater is so easy to use, with no chance of batteries getting low or electronic setting glitches. I love its compact size and, thank-you-whoever-designed-it, it has not only a clean all-white appearance but a matching white cord as well!! (Nothing drives me crazier than an all-white appliance with an ugly black cord that immediately shows itself on the floor against a white wall). But don't let its small size fool you - this little cutie puts out heat, and puts it out quickly! I have a wall of windows in my living room which is always 10 degrees colder than the other rooms in our house, and since I like to read in that room, it always meant getting out a blanket. Not anymore - I can read to my heart's content with the flick of one button and warm up within seconds. Admittedly, I bought this heater because of its pure white color, white cord, and sophisticated design. I had no idea I would love its heating element just as much as its design!
