I bought this for wrapping around a hummingbird feeder in winter. Before you tell me I was supposed to stop feeding them so they'll migrate, these particular hummers (Anna's) do not migrate! I fed them all winter, and they depended on me to fill the feeder to keep their little tummies full. This cable worked perfectly for my needs! I used a large glass feeder, and this wrapped nicely around it. I used electrical tape to adhere it to the feeder, then ran an extension cord to the cable. I love the fact that it has a little "pilot" light that comes on when the temp gets low, and it is visible in the dark. I was so glad to be able to find this, and it have recommended it to others.
