An absolutely great app, thoroughly impressed with it.
Very easy to use with some very good features.
It records up to 60fps with EXTREMELY high quality.
You can record a window, the screen, follow the mouse or a portion of the screen.
You can record with your webcam at the same time, and use the microphone.
You can use hotkeys to bring up your pre-typed words on the screen.
Timers too, and change the hotkeys.
There's lots of ways to export it too.
All in all, the best screen recorder I've used. I've heard ScreenFlow is good though, but I doubt it's as good as this!
