I have been using this device since 9 months. Ita great at first has a fast enough transfer rate and is pretty good at copying a 700mb file in just under 1 minute.
Had copied a lot of mu files on it cos I have lost my 1TB PC harddisk fidelity as it lost one partition and also the data on it which is sad.
Anyway coming to the dissapointment it is loosing connection and frequently have to reposioned to get it connected. I didnt buy the HD for just keep on adjusting and see for connectivity. Its just have to get connected when I tell it to. Has a loose contact when I connect it to PC, Laptop, My smart TV pretty much anything.
