When you are holding your water cup, no one would come to think it is a multi-function cup hidden with recorder and camera. How crazy is that? Basically with its multi-function and motion detection capability, you can utilize them to its fullest. Such as when you are sitting to read, and would like to record your surroundings; record minutes for business meetings; record lecture notes that you can review later on; and record those that you think are worthy of recording, safety and merry to use. Furthermore, the batteries can last 5 to 6 hours of recording time, convenient for usage, and can support up to 32GB of the T-flash card (not included).
