A material with outstanding features unfortunately marred by a faulty assembly quality. My copy, purchased in August 2014 has a loose connection at the rear USB socket on the first try: contact with USB only established positions in certain conditions of the unit or pressure on the plug. I tried several quality usb cable, including some very good marks: nothing works. this is on the receiving part and the moving camera is not correctly set. Contact the customer service, re expedition UK, verdict: nothing wrong, it gives you back your device. Shipments at my expense. Yet I see that without the elastic that I added to hold the USB cable in good position and the contact pressure is not good. Take Me for a c ... those !! but hey, the pictures are really good ... plan an elastic what!
