I'll try and blog this build as it's a new one and I don't think anyone here has built one yet. 
Starting off, it's huge. The main hull section is 600mm. The plastic is a nice quality, however there are injection marks everywhere on the larger pieces, and the smaller parts have significant mould lines to clear up.
There is a weird amount of detail included for the internals...all the hatches are workable, but you really can't see anything inside without a light source, even then it would be minimal, so not sure what the point of 6 dials and a PA speaker are. If they wanted to just show what you can see, then they fail, if they wanted to be anywhere near accurate, they fail. U-boat conning towers were packed with wires, pipes and gizmos. I don’t think they really knew what they wanted to achieve. I am going to attempt to scratch build some internal detail, and see if I can maybe do a cutaway. If I mess it up before the cut, it won't be seen anyway. I have ordered some red micro LEDs…just in case. The open hatches are also devoid of any detail. Here is the progress so far:
Vallejo bottle for scale on a ‘tidy’ bench.

Pin marks and lack of any detail on the hatches:

More injection marks, plus the location for all 8 parts of the interior:

Conning tower details, and the space for the opportunity to fill…

Starting to detail the periscope…again pretty low on detail compared to the real thing.
