This one is great if you're calling a show because it will show you the time AND you can time how long the show is. You can also use it to count down two separate things at the same time (but that seems less useful for me)
I like this because I always forget to check the time during rehearsal, and I forget to start timing the show when I start calling top-of-show cues. Having something big that can sit on my desk makes it easier to remember.
