@Tamamo @beardalaxy yeah, I don't really care about heating, and would never buy a separate heating rod because I know I'll never use it.
It's just that this one comes with one, and it's part of the cover, so you can quickly heat it before opening it up to use, so
I shudder just thinking what may happen if they malfunction. The one I got at least uses an external heating rod, so if anything happens the only thing that will melt will be the rubber onahole, and not my dick.
