2-Line 5.8 GHz GigaRange Expandable Cordless Phone System

This 2-line system works well. I replaced a 8 year old 2-line Panasonic only because the batteries were not lasting very long. The system has performed as expected,unlike some of the other comments I read before I bought this system. Easy to setup and use. I have no problem with hearing using this phone, even though my wife complains about my hearing.

We've had this system, along with 5 KX-TGA670B units, for about a month. So far it's worked exactly the way we'd want. The interface with the Phonebook, and call list could be a little less cumbersome, but they work well. It replaced our Siemens system. The speaker function is a welcome addition. Set up was easy except getting our fax machine (with distinctive ring feature) to work with it, but that was more a function of the fax machine than this phone system.

It would have been nice to know that the KX-TG6702B=KX-TG6700+1KX-TGA670B (as I understand it).

I based on my prior good experience with Panasonic wireless phones but found this one (KX-TG6702)to be a disappointment. Sound quality on the remote is fair at best. Accessing stored numbers requires 3 key depressions to get into phonebook. The "soft keys" are small and recessed. Backlight and small characters make reading difficult. On the plus side the range is adequate.
Overall it's probably the least convenient phone I've ever used.

The phone is crystal clear even at the backside of the pool - The 2-lines are a requirement with family members and independant calling preferences

We use these in a retail store. They are constantly used over a nine hour period. The batteries last all day and the sound quality is always good.
