Title: Very poor range of operation
Review: Even though the manual claims upto 100 feet range, it doesn't work at even 15 feet!. My previous unit made by Desa (that company has the same address as Heath Zenith)was amazingly powerful. It easily went thru four walls. I don't need 64 chimes, just one I can hear 20 feet away. Don't buy this unless you need a very short range of operation. I give this unit only one star.
