Happy
Color: Black+Red
Very happy with purchase. I bought this to replace my son’s otterbox heavy duty case because the plastic kept breaking around it to where it dropped for the last time and shattered the screen protector and chipped the corner of the iPad. This was a fraction of the price and seems way more durable.

Good protection for your tablet.
Color: Navy+Black
Nice case although not as adjustable as my previous one it wears well and protects my iPad well. Its look does not detract from the tablet.

Comes apart easily.
Color: Black+Red
Bought my toddler an iPad for Christmas. Great feel, good quality but pops front pops off very easily when he drops it. I wish it would stay on a little better so I will be looking for a new one.
