I've had a Cuddeback NoFlash out since 12/19. It's seen brutal cold, 10 inches of wet snow, and some unseasonably warm temps (not to mention about 4 straight days of rain). It's been through a 60 degree temp swing over this time. I just pulled the flash card from it tonight. Battery was still at 25%. Since 12/19 it has taken a combined 994 movies and stills, almost exclusively in the dark, which uses more battery power than during the day. None of the pictures or movies were dramatic in any way so I won't bore you with a ton of pictures, but this thing really takes a lickin and keeps snapping pictures.
