Package is now 5 miles from my place at a FedEx sorting centre.
Due to BlackArrow choosing economy shipment, FedEx will keep it there till January 7th before delivering...
I received the package, two boxes in one box. I unpacked one, it contained an X3.
Turned it on, configured it and it works, alas 9 months too late.
I switched it off again. (According to https://bitcoinwisdom.com/bitcoin/difficulty it produces us$0.15 an hour, 1kWh cost around us$0.30 here in Holland)
Now waiting for the VAT invoice from FedEx, will be another us$165 (in Euro's) down the drain.
Some pictures:

The machine itself:


The web interface, using almost 1W per GH/s(I started selling OneStringMiner boards 9 months ago that use at least 20% less).
And notice the errors after running for just a couple of minutes:


The manual, notice the lousy images, too dark, hardly readable:


I also made a short five seconds movie to record the loud noise, but for whatever reason there is only static, so I am not posting it.
