Product review (4 stars): Good temperature monitoring and notification when temperature drops below established ...
Good temperature monitoring and notification when temperature drops below established parameter.  Some glitches with initial set up.  Customer service call requested message be left with return call promised no return call ever.  Was finally able to complete installation on my own.

I did not realize that after the initial set up period (1 year I believe) that there will be a charge for notifications.  Only user initiated monitoring will be available at no charge.

Product is 4 stars.  Customer service 1 star.
