Prime1 miner = A1 clone, same as Dragon, its not based on the Antminer S2
From your web site: "Chip: ASIC A1 28NM, 4 modules, each with 8 chips", Antminer uses a completely different ASIC
This is just the same as all other A1 clone resellers on this forum, delivery from them is 3 days from stock for $1780
So its the same just $500 more expensive.
Just wondering if you realised, might be why your thread is so quiet.
And its the same crappy PSU.
