I received the 0.01 as well and here are the things I noticed while testing:
1. The letter of Guarantee says "We hereby confirm that WWW.BITMIXER.IM has generated the address" when infact it should say "[banned mixer] " but the address shown on the FAQ Page "For your peace of mind we always provide this and sign it from our main bitcoin account 1CrypMixXWtTjYGCM5ZJmyQYP1Y39P7aLM You may verify our digital sign using your Bitcoin wallet. " is the one it was signed from (verified the signature in Electrum), so I went ahead with the mixing.
2. Another thing I noticed in Letter of Guarantee is, it says "100% to -- after 30 minutes." But on FAQ it says "Your bitcoin mixing will be done instantly as soon as we have received your coins.", So one of those needs to be edited. Apart from that, this also needs correction: "with minimum amount of BTC per single transaction and maximum amount of 2001.02 BTC total", it should say "minimum amount of BTC per single transaction 0.01".
3. The QR code and the address shown to send the coins to, mismatch, which could cause problems, although sender should only send to the address listed in the Letter of Guarantee.
4. After sending the coins to the site, the page still shows "Waiting for Payment", when right below that it says "Received 0.01 BTC", it should change to "Waiting for confirmation(s)", OR maybe since the address is valid for 24 hours, it can say that since I can use the same address to mix more coins, so not a big problem.
5. Received the coins seconds after it was confirmed on blockchain, which is good and it did showed a confirmation on the webpage that the mixed coins were sent. The calculator works right, the coins I received were exactly as it showed.

6. Ran Taint Analysis and coins don't show any signs of the original address, which is again good and it passes the mixing test.
The site so far works like it should but requires little tweaks here and there and some correction in QR Code generator and text in Letter of Guarantee. Apart from the things mentioned above, didn't had any other problems.
Thanks for letting me test and please let me know should you need more testing done.
