If there is a bigger waste of money, I don't know what it is. While it worked the sound quality was horroble. It made every call sound like Charlie Brown's teacher. On the bright side, since it doesn't work 30 days after purchase, the sound quality isn't quite as annoying. I give it one star because no stars is not an option. Sad thing is, if I were to slap the manufacturers I would be the one to go to jail.
