The three video resolutions are of high quality very good to good. At the lowest resolution can be taken with a 32GB card up to 8 hours. The limiting factor is the battery here. Either one uses a Accupack (eg EasyAcc) or closing the camera at the same to the electrical system. Then you can record an entire tour. With the included software (for call to the hotline I got the unlock code by e-mail) you can then cut together the most beautiful scenes.
The photosensitivity is good. The camera will adjust very quickly to changing light conditions (driving through tunnels etc.).
The photo function I can not judge. I do not use. Take pictures on the tour mostly by mobile phone.
WiFi-Direct with the Rollei app (Android) is working properly. You can control the camera from afar, or transfer data from the camera to mobile. Great feature.
Two little things that bother me a bit, but do not lead to a devaluation: Both the display and the function LED are not visible in bright sunlight. The function LED personally I would have liked something "stronger".
