Good but By CalgaryGuy on 2/10/2014

The product is pretty sturdy and clamps closed if it loses power. It takes away the 'did I shut it off?' panic attacks at four in the morning or on your way to work.
My only issue is that it does not come with the magnetic holders for the sensors like the ATO units do. It comes with rails to mount the sensor but unless you have a perfectly flat side with access to hang the rail they don't work.
I wish they'd kept the cheapo rails and included the magnetic holders instead.
