If you are going to re-use the same heating pad, you must be VERY careful when you remove it. Take it off as flat as possible. If it bends, you can break the small wiring and coil components within the heater. This can cause the UTH to overheat and endanger your frog. If the wiring is corrupted it will produce too much heat for the tank and possibly even catch fire. Be very careful if you re-use it.
