Title: Worked great, then stopped.
Review: I've ordered 3 of these over the past year. Now, only one works. The receivers all still work, but the 2 of the sensors have been scrambled somehow. One of them won't stop beeping when you put the battery in, the other doesn't ever beep, even with a fresh battery. There were a live saver at first, allowing me to work in the office, and know when customers came in into our tasting room, but now they're going in the trash, after less than a year.
