Cheap in every sense - Without quality assurance

Have the converter bought to connect to a modern PC upgrade set with only one PS / 2 port the existing PS / 2 mouse and keyboard.
As had already read that the key with '' and '|' does not work on this converter, I wanted to at least get the mouse to work.
Unfortunately initially unsuccessful: neither two PS / 2 mice (older with ball and newer laser) two different keyboards were recognized on PC Windows XP (not even in the Device Manager as an unknown device).

When opening the converter housing in the middle (went very easy: just put together without latches plastic halves - just with a knife vorstichtig pry) the cause was quickly found: the cable wires are fast and sloppy soldered onto the small circuit board, so that in this case, a tiny copper veins one short circuit caused. With a small screwdriver bent away, the part went again - temporarily at least. After a while alternating between impeccable operation and no function I have it then can be, since it was intended for the PC of a friend who has no idea about technology and what needs reliable.
Once again an example that the CE marking (the right, not "Chinese Export" ;-), even if that would be more appropriate in this case) is legally not a seal.

The price makes returning little sense, therefore, at all my trial out of curiosity to open the device, of course, the warranty expires.

Conclusion: Stay away! Perhaps what for hobbyists, it can be easily opened and closed again ... ;-)
