It works flawlessly to rid my computer of cached files.

I have has this app on my computer from the first day that I upgraded to Mountain Lion. I also have Onyx on my system, but I enjoy the simple interface to rid my computer of bloated caches, and trash. I will always install this on all new computers from this point forward. Kudos Rocky Sand Studios on a lean, clean diagnostic app!
