The new Panasonic KX-TG 6421 is a great addition the the high quality Panasonic phone range. With a clean and attractive silver design of the phone and base station it was certainly designed with style in mind.

Some of my favourite features on the Panasonic KX-TG 6421 include the hands free use, one button activates the speaker phone. The speaker phone is clear and the sound quality is second to none on a phone I have seen like this. The phone has 20 minutes...
