Antminer S9 L3+ Bitcoin Miner Noise Cancelling Box

HI ---This is a very expensive product and is advertised to require no additional parts and very little effort for assembly.First of all. It does what it is supposed to do: REDUCE THE TERRIBLE NOISE OF THE ANTMINER S-9.Product challenges:1) Shipped with 3 missing screw rods.2) No assembly instructions.3) Requires an additional Flat head Screw Driver to assemble the ventillation ducting.4) Included power plug does not have electrical cable attached.5) Holes in the side panel for the cable and the power are not drilled through the foam, only the laminated board so you will need to drill them if you need them.6) Holes not big enough to fit the standard power plug adapter head, which is why i suspect that they have a seperate power supply socket, but then no cable is included ... only the socket. and you need to split the wires yourself to wire up the socket with a seperate cable that you need to purchase.7) My unit arrived cracked on 2 panels, I suspect it was damaged during shipping.8) Finally the exahust ports are not aligned to the ANT s-9 so you need to use some additional support to ensure that the exhaust ducting aligns with the S9 exhaust port fan. I happened to have some styrofoam lying around so I used that ... it is not included with the bitcoin box.Does it do what it shoud do? Yes!! 5 stars out of 5.Comes included with everything you need?: No ... 1.5 Stars out of 5 stars.This product has potential! Hopefully they will continue to improve it if they get more sales.
