krizwit, I have been using this probe for a long time, and it is still dead on at boiling and on the cold end as well. It is one of the rubber covered wire models, not the metal braid, if ya know what i mean. It is crimped pretty well and I have never had any issues with it.
Its just a cheap one from Target, I think, I cant remeber where I got it, it's been so long.
Peace Brotha!
