As a student microscope OK

My daughter got for Christmas a Bresser Biolux NV microscope in the case. It's a really nice device and you can do some things in order -
But the so-called manual is unfortunately quite useless.
One can the microscope according to the pictures halfway assemble - but then you stand there alone and have to try.
No description of the individual components and how they are to operate.
No description of the accessories and how to order making.
We now have on the Bresser website 2 Brochures found to help a little.
This round "razor blade" - how it is used?
For what the second round part is next in the trunk?
Are there any other accessories that specifically fit into the suitcase?
No description that you can rotate the eyepiece.
Sorry, no attachment for the camera.

Now still positive:
The optical quality is really good.
You can nice shots with the camera make the PC. (See fruit fly, ant)
As a student microscope I would really recommend it - with better manual / documentation definitely.
