I tumbled my coins successfully @ bitmixer.io yesterday. Initially, I was very hesitant due to the amount of FUD on this thread, and its similarities with bitmixer.io. However, I decided to give them a try with the minimum amount, and I must say that they are one of the most secure and professional bitcoin tumbling services I have ever used.

Yes, the website looks kinda like bitmixer, and 99% of websites that adopt this approach are scams. Bitmixer.io is the exception and is in the 1% minority. I say this because after my first mix, I made a lot more transactions with bigger amounts, and I received every single satoshi back minus their fees. I hope they keep this up and are here to stay as the community needs honest businesses.
