This isn't looking kosher if you ask me... I could be wrong, but based on research and communication so far, this isn't looking right...
If they were really scamming, they wouldn't take paypal. It's really easy to dispute a paypal charge that you paid with a credit card.
I don't know about that... sometimes there are teams that do a quick scam, get what they can, transfer monies out etc... and let paypal refund customers.
also they could ship, but what? if anyone is receiving a shipment, video record the whole unpacking process to make sure it's a real unit. until we see working units this has be be approached with extreme caution.
