1. Miracastfähigkeit
2. Ethernet capability (with USB LAN adapter)
3. SIM card connector
Intended use of the device:
1. Mirroring Youtube films on your TV and use the tablet as a general remote control for TV and Blue Ray player. Here, the tablet should depend on dLAN ideally, so that I can leave off the WiFi network, along the lines of: "The less radio, the better".
2. Occasional driving on longer journeys, and then: surfing with UMTS stick.
What was left of it?
1.
Miracast works (DLNA too), but only with some clicking but be called, but there was 1/2 point deduction. Picture quality is very neat.
There are apps for TVs and Blu-ray player. Although not perfect, but the tablet can not. In any case, both devices with the tablet can be controlled without difficulty. It meets my expectations in this regard.

Ethernet connection is not advertised. Here I had fallen for the review of an adapter in which it was alleged that the latter had to work with the people of Tablet. Unfortunately was not the case - now I've tried two adapters without success and a message of Trekstor Customer Service received that the people can only be operated via Tablet WiFi. Bad luck ...
. 3
SIM slot available, but unfortunately only suitable for micro-SIM. My mistake - it was namely also so stated in Trekstor data sheet. Once again, I was taken in by the (wrong) answer to a relevant "Ask a Question" here at Amazon. Anyway: My SIM card is normal size and therefore do not fit in. However, you can at the phone provider allegedly reorder a micro-SIM. Since I'm the normal SIM continue to operate even on a laptop, I buy for the tablet now have a new starter set with micro-SIM. Who is brave and no longer intends to use them again later in the original slot on the phone or adapter, can also cut its normal SIM card itself, are stencils and special devices for ordering here on Amazon.
Annoying: The many preinstalled apps can not be uninstalled - unless you rootet the device, which would, however, then exit the warranty period. That was still 1/2 point deduction. After all, you can see the pre-installed apps, but remove and disable the Desktop. With difficulty, but better than nothing. Especially the PICTURE icon went on my nerves.
Class: The mobile desktop backgrounds. The "black hole" gives the tablet a completely new look.
I had only recently to return the device back, but now I realized that very few - and 2-3 times more expensive - tablets or mini-notebooks are able to fulfill my initial claims completely. When it comes to dLAN and micro-SIM port I would not rely on the reviews of other people, but to investigate more thoroughly.
As such, I am pleased but when it comes to the price-performance ratio in retrospect. So bottom line, a buy recommendation - who puts a lot of emphasis on LAN connection and Miracastfähigkeit, should in my opinion but rather a little wait for further developments. I could imagine that there are in a year or two more choices of notebooks on the market that not only have Ethernet and SIM connections, but are also miracastfähig and their Monitor "is not greater than 13. When's the whole thing even chic are in white and the device is no more than EUR 150 - cost, I might propose at a later date to again, who knows ...
In the meantime I'm going only once further Volkswagen, Rolls Royce instead. ;-)

Addendum of 11/04/2015
The tablet is merrily in use. Would like to point out that it recognizes my wireless only 2.4GHz (5GHz unfortunately funzt not) and that it basically does not display networks with hidden SSID from the list. So it's not possible to hide the SSID and connect to it manually.
