Product review (4 stars): Directions for what ?
The directions that come with these thermometers are VERY confusing. They talk about a CLOCK and an IN - OUT temperature function all controlled by keys marked FSW, HR, MIN. Sorry to say there are NO keys to push or any of these functions on the thermometer. The units ship with 2 LR44 batteries. The directions say to install 1 battery. There is a place in the unit for 2 and you do need both of them installed for the units to work.
