Simple Action FHD camera with best price / performance ratio!

In short:
+ Image quality is OK, despite simple fix-focus lens
+ 120 ° image angle in 1080p (I prefer 170 °)
+ Replaceable battery
+ Rear wall of metal
+ 1/4 "tripod to camera and accessories
+ Infrared Remote Control
+ Extensive, stable accessories incl.
+ Playback via HDMI works flawlessly
o average sound quality
o max. Operating time with WiFi only about 50 minutes! (Excluding about 140 min)
o WiFi is very slow, therefore only suitable for settings / control!

Files can be transferred very quickly to a playback device via USB or USB OTG. (Via WiFi, it works if need be, but is simply extremely slow.)
With Full-HD videos, the file size is about 90MB per minute!

-> For me 5 stars, because the best price / performance ratio!
Notes:
For proper playback of videos on Android devices the "MX-Player" is very appropriate.
A comprehensive instruction manual to the camera can be found (via eg Google) under way, "WDV5000_Anleitung DE"
