hi, we are from the "GoGo Shop" Company.
Let us explain our what we have to say:
first of all, ultimaker 2 is open source.
the licence is CC-by-NC
all the parts for ultimaker 2 is shown in this link:
https://github.com/Ultimaker/Ultimaker2
Now, about what we selling:
this is not a complete printer, we selling only the parts for build your printer yourself.
of course its totally other case if you sell a complete printer and tell that is "ultimaker 2 original".
important to know that most of the parts are common parts. to ultimaker company not have any type about copyrights on this common parts.
only the main parts like the electric boards, generally structure, firmware, etc ...
but again, this parts have a license of Creative Common. so can't say that is
illicit to selling or fake.
the term "fake" it is only for fully commercial product and not under license of Creative Common (except for very specific exceptions, but this is for another topic).
if you want to build your ultimaker 2 and not buy the assembled one from ultimaker company (for save a money if you can't allow it yourself). its can be hard work to attaches all the parts from different suppliers.
also, the quality of the parts can be very different even if look same, also need to verify and check the quality of the parts.
To solve this difficult problem we come in. you can buy in one package all the best quality parts for build your own Ultimaker 2 printer.
There are a lot of parameters, mainly with stepper motors and electron boards, in our we buy from manufacturer that operation the most rigorous testing using X-rays.
Probably, Mr. Shamai does not know correctly assemble the printer and is having difficulties.
we offered him help, but he preferred to open a paypal dispute in order to save himself.
About what you see in the bad looking knob.
its my private reason, actually the printer are come with some beautiful transparent knob frame.
but he wrongly broken me by cocked on it, so i not use it on my printer, that is what you can see on the video.
however, the video have target to demonstrate how our finally printer is do the job of printing and they show very high result model.
