I ordered this case for my new IPad. This case is awesome! Not flimsy and bulky. I loved that it had a screen saver included in the case. It was easy to put on my IPad. Snapped together good. The price was excellent! The case keeps all dust off the screen. The screen is easy to clean. I highly recommend this case!
