Cons

Plain PROMPT='%~ '
has a big advantage over this theme.
Con Slow when working with large Git repositories
Con Prompt screws up cursor
The right arrow used in the prompt seems to be larger than 1 character, but slightly smaller than two. As such, your cursor will either be very slightly offset, or so offset that it is unworkable.
