All in all the app works great. Does what it says it will do. Sounds are of decent quality. My only complaint is that the fullscreen mode doesnt function properly; it does not go to a separate desktop space as fullscreen apps are supposed to do in OS X. Also, no "exit fullscreen" button appears in the menu bar, but hitting esc does the trick. Still, again, solid app, great price. Update: noticed a second, less minor flaw; this application causes Mac OS to switch to discreet graphics instead of integrated (on systems that have both, such as MacBook Pros). This will drain the battery uneccesarily fast.
