Product review (4 stars): Great temperature instrument, but lacks some of the features of AcuRite's other units
Works well as described, but one slight glitch is that I wanted to use it with two other AcuRite wireless indoor/outdoor thermometers, but this one requires it's own separate outdoor transmitter.  My other three units use a code (1-2-3) but this one does not, so will not receive data from the transmitter for the other units.  Because of it's lack of the coding feature, you will have difficulty using more than one of these units in multiple locations.  Also, this unit does not save the days high and low temperatures as my other three units do.  Other than these minor differences, this is an easy to read, inexpensive, and well made unit.
