Title: Reciever disks have been battery burners
Review: I have the older 4 reciever unit. The concept is great. It works well when the batteries in the recievers aren't dead. I've had mine two years and the batteries in the receivers with no use seem to go dead in two months. It's the same for all 4 receivers. They go dead at about the same time. Stock up on the CR2032 quarter sized batteries.
