Bought two of these for outdoor use. Have stayed outdoors (in the rain and the sun) for about two months now and still are working good. As had been commented by others, the adhesion of the double sided tape is not the best. Other than that, the only complaint I have is with the App for controlling this from your smart phone. The issue here is that, there is no way to pair your lights with your app. Because of this, by chance, if your neighbour also gets the same lights and if they happen to be in range, they would be able to control your lights, or you be able to control their lights. Other than that, the app provides some good options on different lighting effects and controls. I'm most impressed with is the brighness of the lights. Overall, I would recommend this product, but I'm not sure about the longevity of it, especially if you're going use it outdoors under the elements.
