Title: Barely worked
Review: This worked for a couple of weeks in this very mild winter, then when it got down into the 20's, it stopped working - solid block of ice in bird bath. I'm throwing it away, since we have no way of knowing if it's just ineffective, or if it has a wiring problem that could cause a short. (I would return it, but we didn't use it for several months after purchase, so it's too late.) Since we liked it while it worked, I would have given it more stars on the chance that this one was just a dud. But there are enough other reviews with similar problems that I felt this device might actually have too many problems.
