Who does not know that? - The constant umstöpseln when friends or acquaintances pressed gets a PC case with the following words in the hand: Kannste times nachgucken ... is not running anyway. For who are a second set of monitor, keyboard and mouse in the corner already in such cases? A simple yet ingenious solution, this device ... I do not want to miss. Side note: According to the description, by the long supply line to monitor the image quality suffer somewhat. For me the image was (just text) slightly blurred, but what could I turn it off to the monitor through a short cable (0.5m) from the switch. Anyway, I highly recommend this device, just for hobbyists, recommend!
