Cuts signal

Arrived well packaged in a cardboard within a week.
Small, light and very discreet because of the power and activity LEDs, as well as 2 side connections impractical.
The hardware installation was fast but the understanding of the system and device management deserves a real instructions with images and configurations. Very practical with its remote control, but quickly heats.

I just return the defective systematically because after a time (from 30 to 2 pm), there are untimely cuts signal. I expect an exchange if not I will take another model.
