Forget or lose your SD card?
Attack/Ambush will still take images and video!
Attack/Ambush can record images
or video in internal memory
(approximately 60 images in
60 MB of internal memory).
This way, if you forget or lose
your SD card in the field, you're
not out of luck.

"Eventually we will all forget or lose an SD card. With Cuddeback you can still get images thanks to its built-in memory/No Card Mode."
