"Why this is better than digital...."
I really like this timer. I always find JosephJoseph products to be good quality. Like traditional egg-timers this one works by being turned. But, unlike the others, you don't have to pick it up and squint to see how many minutes are left! The "pie" design means that you can see from across the room roughly how much time is left. A quarter (of an hour)? Half (an hour)? Just a sliver/few minutes? It's fab! It even stands on its side, upright! There are small lines for the numbers in btwn (e.g. 6-9). Can't wait to use with my son when he is older, e.g. "bath time is done when the white's gone!"
