The miner is in great shape and up and running. Sfminer has two varieties of the silverfish on the streets now, and the one I received from Zighash has the twin 80mm fans. It is about 2/3 the width of the other model floating around which uses a single hi-speed 120mm fan. Hash rate is better than or as expected with the miner currently pushing 29Mh/s on the pool.
Setup is simple, the software for these miners uses UDP ports so if you have problems, check your firewall settings. On power up the miner was instantly recognized and after about 5 minutes of warm up, it was up and running at full speed.
Very securely packaged. Double boxed with heavy foam inserts to keep anything from shifting around and to prevent the box from pushing inwards on the circuit cards in the case of an impact.
