HORRIBLE

Please read the reviews on this thing. It is horrible. Has not worked out of the box. Worst money I have spent. It is off to Goodwill as I cannot take the frustration and constant reminder of money lost. It might have been better but there are no instructions or a way to contact the company for help. Shame on the Apple Store for letting this product be sold. Say I have to rate it will not let me give zero stars.
