MacOS does not get up and running, despite months of effort the manufacturer support. Under Linux, the device works for me. The casing in black lacquer dirty very easily and is difficult to clean. The display is abysmal, extreme viewing angle dependent, hardly read highly reflective and without direct lighting. The connection cable has the incredible length of 30 cm. The cable has no strain relief on the housing. It can be drawn with the lowest strength of the housing hole. One must therefore be very careful never to pull the cable, otherwise it tears from the inside. All in all a grossly overpriced part with plenty of quirks.
