I used this as a thermometer for steaks, roasts and such, and it worked 'OK'. While homebrewing some beer it was submerged in the boiling wort and 'kinda sort of worked' after that. We put it in the freezer to test it and my freezer was a whopping 67 degrees for a couple hours, luckily none of the ice melted in these temperatures. (Did you pickup the sarcasm? I hope so! Moving on.) The more I read about the digital thermometers, I find out most can't be submerged in liquid.I do like that you can set it to a range and it will beep when you leave this range, but I think I have to resort to a trusty analog thermometer for now.
