Im vry happy with mine, though I made the mistake of buying a Z3 compact, a smaller model, something to watch for.
The compact are model numbers 5xxx wheras the larger units are 6xxx.
Battery life tests have shown I can get about 9 hours at full brightness, which must be selected in settings.

Flew with the Z3 for the first time today, under streets and through blue holes-really an excellent modern and affordable device.

Enthusiastically recommend it.
