With a 2-3/4-inch bottom that fits most vehicle drink holders, this lightweight mug makes hot coffee, tea, or chocolate available on the road. Hot beverages stay hot for at least 1 hour. Cold beverages stay chilled for several hours. Twist the finely threaded stopper tight, and the mug won't leak even if it's knocked over. Twist it about a quarter-turn and drink out of either side--lips on both sides make it easy--without removing the stopper. Made of stainless steel and tough plastic, with a rubber inset inside the handle for comfort and a rubberized ring around the body for a firm grip, the mug is handsome and virtually unbreakable. It stands 7-1/4 inches high, and its smooth stainless-steel interior cleans easily with a sponge or cloth. Nissan insulated products carry five-year warranties against defects. --Fred Brack
