Until I received a digital fork thermometer I never thought that they were a necessity; I wasn't sure if they were accurate or even safe to use when grilling. When I am cooking steaks, pork chops or pork tenderloin I always use this thermometer fork to see if the meat it cooked to a safe serving temperature. It eliminates the need to cut the meat open and lose the juices. You can use this for a lot of different types of meat and you can use it while grilling or cooking inside. This is battery powered so it is something that can last for years if you take care of it. When I first got this I thought that it was something that you used until the batteries gave out then you bought a new one. Replacing the two AAA sized batteries is simple but you need to make sure that the battery cover is replaced correctly so that water does not leak into the compartment. This is a fully functional turning fork but when you pierce a piece of meat (or any other food) it will give you the read out of the internal temperature. I'm not too worried about serving steak or burgers on the grill because everyone likes them a little on the cooked side but when it comes to grilling pork chops or tenderloin I want to make sure that they are completely cooked without leaving them on the grill for so long that they are dried out. When you unpack this there are small plastic covers on the end of the tines of the fork; make sure you remove those before you turn the thermometer on or insert it in to meat or any other type of food.
