I've used my digital thermometer for about six years and I had to replace the probe once because of and accident. I will never be without it. If you like your steaks cooked to perfection, this tool is a must. You get an instant and accurate read out. It will make you a pro. I use the 4" needle probe and it works for everything from chicken, hamburger, steaks and roast. Also great for candy. You can also check your hot water and ambient air temperature with extreme accuracy. It has too many uses to describe them all. I'm now buying them for gifts. Like I said, it's a great tool.
