Product review (4 stars): great liquid temp readings
It may be a bit excessive for my application, which is to monitor beer temperatures in my kegerator, but it works very well.  It really helps take the guess work out of liquid temperature readings and monitoring performance of the cooling system.  The probe cable length is perfect at about 10ft and allows me flexibility.  This model takes one AA battery which I am sure will last ,but it would be nice to have a plug in option.  No issues so far and I would buy again.
