Input: Consider Input: Piece of junk! If I didn't take so long to use it....on my New iPad Air 64GB, I would have returned it already....the price wasn't bad, but I was shocked because Sharkk has always come through.<br /><br />The iPad Air doesn't recognize this product and there is no &#34;software&#34; update.

Output: Negative Review
