OK, got it home and did some testing:

Summary:
+ appears sturdy and well made
+ scart plug sockets are very tight
+ can be used horizontally or vertically
+ autoswitching works great, much more convenient than throwing switches.
+ 9V DC power supply onboard, could be useful for e.g. proper RGB input selection and aspect switching (the idea would be to mod it so that pins 8 and 16 are never forwarded from the inputs to the output and just put the 9V to pin 8 and from pin 8 a 180ohm resistor to pin 16 on the output so as to always have rgb selected and 4:3 aspect ratio enabled)
Now for the major bummer:
- the picture is slightly less bright / duller than when using a standard cheapo manual scart switch (such as e.g. the Carrefour one also visible unplugged in the photo).
For the above reason I can not recommend this switch and will either be putting it up for sale or maybe opening it up and seeing if I can utilize it for something / mod it.
