Product review (3 stars): If I had to do it again, this model would not be my first choice.
Got this as a gifte and was tickled to finally have a unit that did all the things I wanted.  It is a shame that less than a year later, the humidity part of the outside sensor has failed.  We will be filing warranty but there is no excuse for a failure this quickly.  The other thing is the clock is very small and cannot be read from a distance.

If I had to do it again, this model would not be my first choice.

Update  They do get a star back for having spare sensors cheap.  I decided it was easier to buy a new one for 12.99 than worry about warranty.
