I've got two of them. It works great but I went through about 5 probes before I realized that liquid was seeping down into the metal part of the probe and damaging it. I finally started putting some shrink tubing around the probe where the wire is crimped into the metal part.
If you end up needing more probes there's an e-mail address you can contact on the Oneida site and they will replace the damaged probes.
Also, don't drop it in your wort. Tends to make the buttons sticky and one of mine will only read in Celcius now.
