Bought this about 7 years ago. Used it for 1 year because I had to charge the batteries every other month. I tested it out with extra batteries to see how long it lasts and it goes for about twice as long or longer depending on your settings of quality.
Once I moved I hide these away in my closet and just found them.
One camera’s light for function setting is cracked but it doesn’t affect the operation or quality of visual in any way. Comes with everything but the extra batteries. I sent those back. Very expensive batteries!!! Ring quality Batteries alone are $50 a pair. So just in battery value this pays for itself.
