Query: I wish you had a ZERO STAR RATING!

THIS PHONE IS THE BIGGEST RIP OFF I HAVE HAD OF ANY ELECTRONIC PURCHASE. I THOUGHT THE PANASONIC BRAND PLUS ALL THE HYPE SURROUNDING THIS PHONE MEANT IT WOULD AT LEAST FUNCTION PROPERLY IF NOT OUTSTANDINGLY...BUT THE BATTERY LIFE RARELY EXCEEDS 1/2 AN HOUR AND HAS CAUSED MANY DROPPED CALLS. ONLY THE SPEAKERPHONE IS WORTH USING UNLESS YOU WANT TO HANG UP ON THE OTHER PARTY. DONT BUY IT!!!
