The Panasonic KX-TGA 551EB Additional Handset is a value added additional handset with an ergonomic handset design,four line amber backlit display and 100 name and number phonebook. It also features 15 polyphonic ringer tones, speakerphone, lighted keypad.
The usual good quality product from Panasonic and interacts seamlessly with our older Panasonic handsets (I had to download instructions from the net as it came without). As previously mentioned, the volume control is very useful for those of us with slight hearing loss.
