After initial tests and a durchgefilmten holiday I am more than delighted with the Action Cam. The photos and the videos are very good quality (1080p with 60Bildern / sec).
The operation is very easy for an Action Cam to understand. By quite a few buttons a setting on the Cam is straight forward. When shooting with the underwater housing the reduction to 3 buttons makes sense and does not pose any conflicts. There are LEDs that indicate the status of whether or not recording ... that helps the Rollei 6s Wifi on virtually every page.
The compatibility of the action makes it possible to use also other stands / holders etc..
The underwater housing is very robust and has an option to connect an external microphone.
The battery actually holds by the 2.5 hours that are touted. Could not believe it, but I have reached several times.
The ads on the Cam help themselves to identify which mode you are and how many photos / videos you can still pick up (not of course in Actioncammarkt).
All in all I'm very pleased with the acquisition, the cam can only recommend !!
