My initial reaction to AMFEIX was: this seems to be too good to be true and then it usually is. Something in me wanted to give it a try and back in June I did my first deposit of 0.2btc. Until today the service is operational and withdrawals etc just work. Ofcourse that is no guarrantee for the future but as each day passes they are building their track record.
I did a more extensive review and analysis at: AMFEIX review and analysis.
