No time / date stamp in the recordings - useless as proof for german law!
The product arrived safely and responded very quickly, but unfortunately this product cannot be changed in time, so it would be difficult to use it in countries with a time difference from China. Some suggestions for improvement were given, but none were resolved. Although a small refund was offered, it was unfortunate that such an evaluation had to be made because the time could not be set and it could not be used.
