Heat rocks, like many things in this hobby, seem to be surrounded by unfounded claims. Everyone says they are dangerous, but yet I dont know anyone who has ever actually used them and had a problem. I know Al Coritz has been using them with a lot of his hots for years. Where does everyone get this information that they are dangerous from? (Besides just from someone else telling them they are dangerous)

@ice#1: what thermostats are you using that DONT have a remote sensor/probe?...
