Is your lover hot one minute, then cold the next toward you? Then tell him or her to take it out on this Hot & Cold USB Coaster Control. It lets you keep your favorite beverage hot or cold—just the way you like it. It's completely USB-powered, so you'll need to plug it into a free USB port on your computer. It's said to heat up to 104 degrees (Fahrenheit) and chill down to 59 degrees (F).
