WHAT A WONDERFUL DEVICE,I HAD A PORTABLE BLUE TOOTH DEVICE THAT I HAD PURCHASED, SOMETIMES IT WOULD WORK AND SOMETIMES IT WOULD NOT, SO I READ ABOUT PARROT BLUE TOOTH DEVICES AND DECIDED TO GIVE IT A TRY, WELL AFTER A WEEK OF USING IT I AM VERY IMPRESSED. THE UNIT WORKS THRU THE BOSE SYSTEM IN MY CAR AND ALWAYS PAIRS UP AUTOMATICLY WHEN I ENTER MY CAR AND DOWN LOADS MY TELEPHONE CONTACTS AS WELL INTO ITS MEMORY , AND THE SOUND QUALITY IS EXCELLENT!! MY BUSINESS CALLS WORK VERY WELL BOTH INCOMING AND OUT GOING, PEOPLE TELL ME I SOUND AS THOUGH I AM ON A LAND LINE PHONE, AND CANT BELIEVE I"M TALKING TO THEM ON A BLUE TOOTH DEVICE. I MUST ALSO SAY THAT THE CALLER I.D. IS VERY NICE AS WELL, SO I CAN GLANCE DOWN TO SEE WHO IS CALLING AND DECIDE IF I WANT TO TAKE THE CALL OR  NOT. THIS REALLY IS A WONDERFUL PRODUCT, I HIGHLY RECCOMEND IT........
