Want to wait to see how product preforms over timeI used to use my porch light to light up my from just for safety reasons. I'm not sure but I'm estimating it cost my about 15 or so dollar per month. Now this turns on automatically in my front and doesn't cost me anything but the original price I paid for it. Definitely would recommend this.Great motion lights for any dark areas. Works perfectly.It gets charged in the morning and give you light when it is dark. Installing is very easy and hardware comes with the lights. Sofar i am loving it and holding the light for very long period .These lights are awesome!!! Very bright and you can set the motion detection to stay on as long as you like!!! Would buy againJust moved it to my new place and there's no lights in the neighborhood. This was a great purchase and now I can see at night when things move byGot them for my dad as a Father’s Day gift. Easy to install. Very bright light. Motion detector is good. He loved them and decided to order more.I installed them and let them charge for a day and they will not work. I am not sure if I am missing a step but they don't work.I like it a lot. I use for areas that needed the most lights around the house.
