The device really does offer a wide range of functionality and the surface can also be of less experienced users operate. The volume is a bit noisy as I thought, but remains in tolerable, but not necessarily suitable for a living room. For a quieter fan I would definitely spent a few euros more. However, what actually really bothers me a bit that there are hours of accesses to the plates for no apparent reason. That means even if I have not been accessed for several hours on it. One explanation I have not yet. Copying actions from the computer to QNAP are painfully slow. Corded improved something. But I will once I filed and organized my data have again remeasure accurate.
