Q: 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.

A: Negative Review

Q: This is a great buy, I looked at all the reviews and this was the best buy for the money. I had bought a mini keyboard from Staples I am going to take it back. This one the keys are easier to type on and it works with most of the functions of the nexus 7. You really can't go wrong with this device.
