This is not a knock on the product as I have a huge collection of Thermoworks products. However, I think unless you are working in a restaurant kitchen or doing a lot of BBQ contests and speed makes a difference for you it is not worth spending the money for any of the Thermapen products. They have a few other semi instant read hand held thermometers for a fraction of the cost that work great. They are the go to items in my arsenal. I like a thinner probe needle for chicken breasts, burgers, steaks, etc. I even use them for chuck roasts, briskets, and chuck roasts too. I own an MK4 and I am not even sure I have ever used it.
