I volunteer to evaluate products for 3M, and the company recently sent me a free sample of these outdoor light clips and they are great. I have used other command hooks to try and accomplish hanging up lights but they never held the whole season and didn't hold the lights up well. These clips hold the light strings perfectly and I don't think the clips are going to come down until I take them down. I'm so excited to take my holiday lighting to a whole new level. I look forward to all the new products that 3M comes up with.
