YJ Pocket Timer

YJ has developed a super cool pocket timer. The timer uses an infrared sensor to detect the movement of your hands. To use the timer, simply put your hands within 4 cm of the sides of the timer. Wait for the indicator light to turn green, then lift both hands to start the timer. Put both hands down once you're finished solving. The timer features a function button that allows you to see your average of 5 and average of 12 solves. 

At less than 2 cm thick and made of smooth plastic, you can carry this timer in your pocket.
