Clips are perfect for shingle installation. Tight fit to the shingle. I have not had a single bulb come loose during the winter winds that blow across the roof line.
Clips worked just as described. I used them on C9 LED string lights and they worked great on both my gutters and attaching to the shingles and the lights are solid and secure.
These clips are great to work with and easy to install. So far they are working well to hold position on gutters and shingles in our high wind area. They give a nice uniform look to the light setup and I can run two different strings of lights on the clips at the same time.
I loved the product but the boxes were all short of the purported quantity by at least 10%. Called to get the missed product and was sent another box of 100 that only had 95. **Customer service notes: Sorry for any inconvenience. Replacements were sent. The box that was sent was counted by two people and verified to contain 100 clips before shipping. Remaining stock for 2016-2017 has been verified. **
