When ordering such, I was struck by this device that by its price and demands that was exactly where my ideas hingingen.Nun good, I ordered the part, fast delivery was announced and completed, so that I in the installation, shortest time, could begin. First very nice small and install the cable quickly, also the power supply excellent small, you do not need two sockets more. The unit worked immediately without installation materials and works at full capacity. I could not determine whether there are any disadvantages or even power failures so far. So far, the unit operates at full satisfaction and beyond. I could recommend any device. If the price-performance ratio to remain so, I intend soon to buy even several.
