IT skills required

This was my first NAS. He was to secure existing and future data (documents, music, photos and videos), centrally store and provide convenient for the whole family in the home network as a DLNA server. The review is aimed at prospective customers without deep IT knowledge or strong IT affinity. I use both professionally and personally very happy and almost daily PCs, but would describe myself as a user without claim to penetrate the underlying technical details, "or simply as consumers themselves. So I had a professional supportive of the establishment of the NAS. In the end, ran everything, but the path to it was too difficult. I have the device (perhaps unfairly) not testing conceded and returned it back. Delivery and returns through Amazon, as usual, exemplary!
Four stars because the technique according to the other reviews can afford what is advertised and is only my personal demands on the ease of use does not do justice.
