A very smart system

This system is very "smart". The first thing I did was set the time on a handheld without even opening the manual. Lo and behold, the time appeared in all four displays of the system that were scattered about the house!

Very satisfied with the quality and ease of use. The system also operates as an intercom between any two handhelds. Handhelds are nicely backlit and easy to read and operate. Battery life is vastly improved over older technology. An excellent value for the price. You should upgrade even though your old clunker is still working. Made in The Philippines and not China.
