I had good luck with indoor clips last year and was excited to see an outdoor line, which I thought would allow me to put strings of mini-lights around my windows without using nails or otherwise causing damage. I followed the installation instructions carefully, but the adhesive does not stick to the aluminum cladding around the windows. Nearly all the clips popped off when I tried to install mini light strings. Temp at the time was around 45F. A waste of money.
