Product review (2 stars): A low temperature alarm as well??
I should have know for the price, that this would be a piece of crap... but I thought, heck... how complex is a little digital thermometer?

Well, this one works OK as a thermometer... I haven't verified that the temperatures are accurate, but it seems to work ok. However, the alarm doesn't work so well. I bought this to monitor an upright deep freeze we have, in case the power went out to it (circuit tripped, etc.) It turns out this alarm seems to go off at too COLD of a temperature, as well as too warm... for cold, it seems like anything below maybe -8F and the alarm goes off?? Our freezer normally runs at -10F or -11F, so the alarm is constantly on... (useless) so we have to turn that off.

The other thing is that the cord for the probe is a little too big in diameter, it causes a little leak on the door seal, which makes a bunch of ice & frost in the freezer, which worsens the seal... so I'll probably be ditching this temp gauge altogether...
