Customer Review: works extremely well, but poor instructions
This wireless indoor-outdoor thermometer works as advertised. Its remote sensors have very good range and seem quite accurate. It was frustrating to set up because the instructions were not very clear. Once you figure out how to set up the sensors and base, you should write down how you did it. If you don't write it down you'll get frustrated when you have to change the batteies in one of the sensors.
Customer Review: Works but manual is terrible
This unit works as advertised but the manual is awful. Be prepared for some experimentation. When the indoor receiver stopped displaying the outdoor temp, it took me a while to figure out that the receiver's batteries were low. A good manual would greatly increase the value of this product.
