A few little quirks, but quite useful - menu explains ...

FOR QUICK READER (TL; DR)

I really liked:

-Bildqualität (Even with motion)
-Built Color screen.
-Incredibly Lots of accessories.
Battery pack exchangeable.
Etc. -Wifi coupling to a tablet possible ("iSmart DV" app).
-HDMI Output.

Appropriate for the price range, but not optimal:

-Battery Life (60-70min @ 1080).
-No Image stabilization.
-mäßiges microphone.
-Photo Function rather below average.

Bad I found:

-no Timelapse function.
- "Auto Mode" (see text) not properly understood by me.
-G-Mode incomprehensible.
Motion sensing too sensitive.

Summary: I like the product. Even if some things do not work the way I expected. But that only applies to functions that had little relevance to me.
