The installation went well out of his hand, but could have been a little clearer, but this (not included) can be solved by the manual.
As already described by some others here, the link station generates a running vibration, for example, carries over to the desks, shelves or cabinet and so unfortunately is clearly audible.
Back the NAS goes however, because the promised "on and off according to schedule" (see Product Description Amazon), does not exist. This seems to be a problem of the Amazon statement as I could festellen on other websites. A great pity, as this was a major reason for my purchase.
In order for the NAS declines and the search starts again.
