Works well.
I like the "Red Arrow” style the best, at 0.5 transparency. It allows me to see the mouse pointer without blocking the text or tool tip behind it. Originally I wanted to use the pointer enlargement feature that is built into OS X, but the enlarged mouse pointer, when used in GarageBand, actually blocked some important tool tips that were displaying the audio parameters. A semi-transparent pointer gives me the best of both worlds.
