Just a reminder that when using a Bitcoin mixer you should ALWAYS measure your taint. Taint is defined as the % of funds received by an address that can be traced back to another address. So if you sent from address A to a bitcoin mixer, and the mixer forwarded those funds to address B, how easily can the funds in address B be traced back to address A ? In simple terms, did the mixer do its job?
You can measure taint here: https://blockchain.info/taint/
Most mixers do a VERY bad job of mixing your Bitcoins. Be very careful when using a mixer and always check your taint. Reviews of mixers can be found at http://BTCMixers.com
I personally recommend https://CoinMixer.net as my favorite.
I would consider any site endorsed by him to be a scam and likely to be run by him.
