So I had 6 of these from a different vendor. Love these style lights.
This brand was great and would be my top pick of the 3 brands I have bought.
However I did knock 1 star off as one of them were missing a stake for the ground.
I am going to reach out to the company and see if they can make this right if they do I will update my review.
Otherwise the ones I have up last all night till the sun comes up.
It automatically turns on and off
Previously purchased ones have lasted 3 years with no negative effect from the weather or use. I would expect similar results. As long as they make this right this. Company will be my go to for lighting products and I use a lot of lights.
