Title: Poor product - Ordered 2 and both failed
Review: Both base units failed and just had loud continuous beep after being powered on. I drove a mile or two away from my house to see if it might be getting crossed signals from something else. I would have been happy if one base unit had worked, to serve both sensors.They were 12 bucks a piece, so all the time and trouble to send them back would be more of and expense than just eating it.
