Wavy-rubber grips enable a steady hold, and a 360-degree lid lets you sip at any angle, but a recessed screw-top makes it difficult to tell if the valves are open or closed, and twisting the lid into place is a two-handed operation. Though it only kept our coffee warm for four hours versus the competition, the Bodum is the nicest looking of the bunch, and the grip comes in four colors (lime green, red, white, and black).
