1. Pay with a credit card (and not have your Paypal account associated with it)
2. Or you can login to your Paypal account and then pay for the item (just be sure it is a credit card they have associated with your account - not your bank account, debit card or an existing Paypal balance).
I'm not sure which one would give you more protection -- as I'm not a big fan of Paypal in how they handle disputes in general.
Anyway - I feel confident that this seller will deliver on time. It's not like the Hashra units are using some new advanced technology. The chips are 28nm. The power usage is a little less than the A2 Terminator units - but it isn't set in stone [as their site says "Approximately 600w (+ or -10%)"].
I definitely will feel better though if an actual unit is shown running. I think they are just waiting on the enclosures.
I wonder how many units are being produced and sold.
Curious too if anyone has experience on having to pay duties when shipping from China to the US?
all toll - I've about had 12 deliveries to the US from China - only once out of 12 times did I get an import duty bill from DHL and it was for $40 on 3 Rockminers from Zoomhash
the chinese suppliers are pretty good at describing the units so they aren't subject to import duties here in the U.S.
