Product review (3 stars): OK for remote indication if you don't get hung up on accuracy
Inexpensive and easy to use but the accuracy is disappointing.  The outside sensor disagreed with a AcuRite bulb thermometer by 7 degrees.  I placed the remote and the base unit side-by-side indoors and they also disagreed by 7 degrees.  After a month, they seem to have converged to within 1 degree so I'll try the remote outside again.
