you have to know what you want

Mini description of errors and no manufacturer information. From the description you can everything. Image quality is good, reading good, function automatically ON when connected to a voltage (12V car socket) only works with regular use. With more than 2 days of non-use int. The battery is dead despite automatic shutdown. So newly put into operation are also the date and time !!! away. A big + point there for the holder and the adjustability of the system.
ergo price and performance fit, one can not expect a professional material
