The devices themselves are of good quality, image size and resolution are very good, only the totally inadequate and laboriously assembled fastening straps are really inferior. Unfortunately, the monitors are always been run with headphones because the maximum sound volume for the (very quiet) moving car is much too quiet. With three children in car accessory plug and a third headphones are therefore necessary. Unfortunately, both the original broadcast as well as the replacement shipment after each requested the monitors "A" defective. Annoying, because the holiday travel thus virtually fell into the water for the children. Now we have asked for the second replacement shipment - if then something is broken, the monitors go back.
