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!

Good for my needs

Color: Brightblue

I love it but the pop out stand can be a little difficult to maneuver. Otherwise it was easy to install. I removed the clear film that is a screen protector just because I already have issues with contact on the glass.
