Following the instructions on the web site, I was not able to hear any sound. Then it started spontaneously quitting whenever I tried to play an audio file.

The UI is very strange - completely unusable. Funky dials that you're supposed to twist - wit a mouse?! And the entire window vanishes whenever the app is in the background.

Of course the fatal usability issues were not a problem for me, because I couldn't even get the thing to play a sound!

Completely useless. I also had to dig through my /Library/Receipts folder to find out what it had installed and uninstall by hand. What junk!
