Panasonic - Best Cordless Phone System I have Ever Used of Seen
My Panasonic 5.8 GHz phone system is the best one (consumer) I ever had or have seen. I got it at Costco for $149.99 (on sale, $50.00 off, plus instant $50.00 rebate at the register; normally $249.99). It came with the base (digital answering machine and full function phone), and THREE handsets with two handset charging base units (one of the handsets charges on the base unit). I think I will go buy another set, give the base and one handset to someone (in-laws) and add two more handsets to my system.
It is the KX-TG5583 model (base) and KX-TGA551M (handsets).
The range is halfway down the block (in suburban setting) with crystal clear com. The handsets have color LCDs and selectable multicolor light-up stubby antennas. The handsets can communicate with each other like walkie-talkies. I can retrieve my answering machine messages from any handset. The handsets have built-in speaker phone and duplex headset jacks. The handsets last about two days without a charge. The handset and base has talking caller ID. One can purchase an upgrade model of the handsets that has a USB jack and capable of uploading ring-tones, wallpaper, and more; and has a higher resolution LCD.
I have ran multiple tests and have not been able to pick up any of the transmissions, using both my Uniden BCD396T (Close Call and built-in frequency counter) and my frequency counter, at both the handset and base. The package info claims that the system uses 5.8 GHz digital spread spectrum technology.
I have noticed that Panasonic changes its phone models about every three to six months, so this model has already been replaced by one that has the exact same features.
For $149.95, this was awesome!!!
