Received product on time. It has very good picture quality as described by seller. Night vision is so so. I would not recommend this product for night capture. Yes it works if there is some light.Battery life when I tested was 2 hours and 15 minutes. Since I am not interested in picture taking with this so I never tried and have no idea how good or bad it is.Easy to use for using camera. Three basic things you need to do. To turn it On, press button for 3 seconds and light will turn on and then it will blink and then light would turn off. Means, camera is recording. During recording if you press button one time then it will go on standby and you will see a solid blue light. To start recording again from standby, just press the button one more time.If you want to turn it off during recording then press the button for 3 seconds and camera is off. Oh, you cannot record while charging. As far as price is concerned it is an awesome product in that price. Very good quality video and audio recording.
