I tried mixing my 0.002, i send them to 1AuxV8TGyHE1LD5UpPgtLaf8iyPCtbuzBJ, and received 0.001844 back @ 114CbUvt81K4p29WhqeTtGKbRe6XLY5V4H
As you can see, 0.000156/0.002*100 = 7.8% fee, which is quite hefty to be honest, especially if i were to do lots of small transactions. (Since i obviously wouldn't really trust them with bigger amounts yet)
The entire bankroll of this mixer is stored @

That's a hell of a fee to pay for tumbling some coins...
OP, I'd be interested in testing your mixer, but not at the rates that @AdolfinWolf has specified, especially considering that the service fee shows a maximum of 4% on your site. How is the transaction fee specified when returning coins?
