A very good tool for roasting meats without fear. This thermometer comes preprogrammed, but it's easy to amend the presets if you choose to. It is very easy to understand how to use and I especially like that it has an on/off button (my old thermometer didn't, I had to take the battery out to shut it off). The first thermometer I received didn't function properly so I returned it to Cooking.com. They shipped a replacement to me right away, and their customer service department kept me apprised via emails during the exchange process, which I was very glad of. I would recommend both the product and Cooking.com without hesitation to my friends, and indeed have done so.
