These lights are great on my deck gazebo. They light up nicely, are weather proof, and seem built to last. the app requires a smartphone and some technical skill. The features in the app are endless. Likely more features then anyone typically wants or needs. Still, more is better. And I set it for some serene fall colors and they look great. I'll update this if they break. I leave my lights out all winter. We'll see. so far, so good.See full review
