Product Review: ASICMiner Block Erupter Cube Bitcoin Miner: Great Design, High Performance, & ZERO Hardware Assembly Quality Control!


 
 >>Warning<< You do need basic computer hardware (A+ related knowledge) to get these repaired and functioning.
Do NOT turn these on without opening the case and inspecting the integrity of the screw torques, seating of the cards, and the attachment of the heatsink. You could literally fry one if you turn it on without opening them to inspect and repair.

That said.. These are wonderful devices, from a number of perspectives.
- They perform at 38 to 42ghash. We regularly get up to 42ghash on Bitminter, and rarely dip below 38ghash.
- The cases all fit together nice and neat. No need to fiddle with any erector sets as with some other products.
- Config UI is up to par.
- Cooling Fan does it's job.

Cons -
- These were priced at $1170 not more than 3 weeks before this review. As of today, they are at $650.
- Two vendors have both sent product that required disassembly/reassembly. One vendor claimed to have delayed shipping to inspect the units. If that is true, they need to polish their inspection skill set. ;-)
--Without exception, the Units arrived with parts rattling around in the case, two screws actually fell out of one of the devices.
-- Most had to have all the internal cards reseated.
-- Several heat sinks were not firmly attached to the boards, greatly reducing their heat removal efficiency.
Other comments:
All  units had heatsink screws that were NOT torqued. The thermal conduit layer between the sink and the board possesses a modulus of elasticity which should degrade the prospect of the screws becoming loosened due to lifespan.  That was 4 out of four screws on every board of every unit. Only one unit did not have any screws rolling around although 1 screw was only half way in.
