Product review (3 stars): Sensor may be the weak link...mine failed after 2 years
As others have noted, the sensor seems to be the achilles heel in this product.  My first one lasted two years.  I will be interested to see how long this one lasts.  It is all solid state so I have to wonder if the company has "programmed" a predefined failure rate for the sensor.  VW figured out a way to defeat their diesel exhaust tests....This product is important for my household harmony...my wife has a driving interest to know the exact temperature outside...maybe it is because it falls on her to walk the dog most days!

I bought this unit again because the sensor will transmit to multiple base stations.  I now have two monitors and one sensor...that hopefully will last longer than 2 years this time.
