A Little odd thing ..that ads a bit of "I don't know what to call it" but it's sounds great. I used it on vocals which probably is not the first thing one think of using it on. Makes them sound somewhat slightly synthetic. I give it a 10 because it does exactly what it sets out to do, even though in a very narrow field.
Very brief review, but i'd give it a 9 or a 10 myself as it simply does weird and wonderful things to the sound fed to it, in a very simple to use manner. I particularly love it on drums, and recommend it :)
