this guy has already been refunded and is only attempting to spread misinformation about atomic.  Are those sockpuppets replying to his own posts? I can say i have been using it for nearly 2 months now and have found it to be a very safe and reliable exchange.

I have been able to deposit and withdraw bitcoin and other altcoins regularly from there with no delays or issues.  

They also only charge miner fees on withdraws which means you only the pay the default tx fee that a coin may have and not what what cryptsy, mintpal and others demand you to pay so they can profit more.
