I bought a shower gel hidden camera that was advertised as working for 16 hours on continuous recording mode. It doesn't go beyond 2 hours. every 3 minute of the recorded file is 500 Mb! So even if it worked for 16 hours, the memory of 32 Gb will be filled in 2 hours any way. The motion detection is unreliable and doesn't last much longer any way. Don't buy anything from here.
