I think I've been using it for 3 years. (possibly 2, I loose track of time.) The one time I didn't use it, I used electrical tape b/c that's what I use to secure the connection of the cord to the pad. It was a huge mistake, cause the E-tape did not stick to the fabric well, resulting in some spots where chicks could get stuck in the tape. I found that while it didn't stick to fabric well, it stuck to chicks extremely well. Thankfully, I found the missing chick. Ever read the story of Br'eer Rabbit and Tar Baby? well that chick re-enacted the whole story. So, I'd say that painter's tape is great for taping the fabric (I use cotton sheeting) over the whole assembly.
