CL2015 DGT Easy Blue Chess Clock

So what does a chess clock like this DGT model do exactly? Well great question my little confused friend. sometimes, in the game of chess, your opponent is too stupid and ignorant to make a move, thus resulting in you sitting on the opposite side for 3 hours while they deside wether to move left or right. Because of this fact, people began getting annoyed, thus the invention of the chess clock. It times your friend, and when time is up, yells at them to make a move. very effective for people with short attention spans.
