Product review (4 stars): One worked the other had issues but replaced now.
I previously rated this with only one star due to some product problems and a little slow responses from Chaney however they have now sent a replacement.  I actually have two units, one in my home and another in my condo in Canada to keep an eye on the temperature there.  They both originally worked fine but after an update the one in Canada quit working.  It took a number of phone call and e-mails however Chaney did send a replacement and for that I am grateful.  I do like the product and its capabilities and would have given this 5 stars except for the product issues.
