Firegoat - no problem. I only thought I’d bring this up as I have just started using a reusable one. One more important point about the disposable ones is that apparently they get much hotter than the reusable ones. The majority of the ones I have seen come with warnings to not put them directly next to one’s skin. So people should be very very careful with these. The reusable ones are very safe IMHO - I use mine directly on my skin.
