Braun CoolTec CT5cc

Rating: 6

This shaver is outfitted to eradicate skin irritation: Sandwiched between its blades is an aluminum panel that drops to a face-cooling temperature as soon as the power button is pressed. The idea is that the cooler your skin, the less likely it is to redden. It's a neat trick, and we certainly felt the cooling effect during every shave. But the additional tech adds more weight and noise: The CT5cc was the loudest and least maneuverable of the group. If you have sensitive skin, it's a worthy option. [$200; braun.com]
