Thanks for all the replies everyone.

I've used a wide variety of heating sources over the years but I figured with a forum I can get some feedback from others based on their experience of items before I go out & try something new. After a while you get tired of experiments going to goodwill or the trash.

I'm about to purchase a few new pads for some temporary setups. Since I was I thought I might try something new if I got some good feedback on them. I need them to be versatile & have the ability to be reused in different applications since initially they will be on temporarily setups.

Thanks again all

If anyone has any other info please feel free to post.
