Lights are incredible. Have had them up for about 3 weeks. I used the clips at every light and put the two screws in every clip during install because it was below 50 degrees outside and adhesive doesn’t work below 50. Took a while to do it but I think using the clips and screws is the best long term thing to do anyways. Aside from the time it took to do that…. Worth every penny we spent on them. App works great and is very user friendly.
