Title: Be ready to replace it.. over and over and over
Review: This unit works great.. for a couple of months. I don't know if it's the rain or heat (neither is suppose to bother it), but after a couple of months, it simply quits sensing the barking. It gets to the point that you have to hit the sensor hole directly to get it to even trigger. In addition, the label starts to shrivel up.. a sign that it can't really handle the weather. I've sent 7 of these back.. now Smarthome is smart enough to not even carry them. Stay away from this dog.
