I’ve had problem after problem with these lights. I have 2 sets for my sidewalk since my sidewalk is fairly long. In the 2 years I’ve had them, I’ve had one whole set replaced, in addition, 3 of the other 4 lights hae gone bad. Also had to replace the power cable in one set and the “smart” module in the other. I’ll give anker credit that they have been fairly responsive and have sent me what I needed but the last time I’ve had a light go bad, no response yet. I’m regretting choosing this brand and may just go with classic pathway lights. Forget the smart features. The scheduling in the app is confusing, sometimes the lights come on when they are supposed to, sometimes randomly, sometimes never. Also I have yet to see a way to sync the two sets together so the light pattern starts at one end of the sidewalk and ends at the other, currently it goes from start to middle and middle to end. Do your own research but maybe look elsewhere
