Thanks!
I was going over that site and cam across this product:
http://www.reptilebasics.com/ultrath...ter-uth-11-x11
I only have the 1 Ball so was wondering if this is a safe option? I am super leery of anything with the name of "heat tape" from seeing so many fires caused by water pipe heat tapes here in NY. If I went with this product, I would use a thermostat also.
