The original probe which came with the set can catch fire! The high temp plastic (silicone?) jacket on the hot end caught fire and destroyed the probe when I inserted it too early into a tri-tip roast that was still flaming wildly. Live and learn. If the meat is flaming heavily, wait until it subsides to insert the point. This purchase replaced the damaged one. They have changed the plastic jacket to small replaceable silicone rings and include extras. So I suppose mine wasn’t the only one that caught fire.
