I should have known better than to order and try something that looked like it was rushed to market.
Yes, the case is rugged. Yes, it can be secured to the back of most car seats. No, it does not hold the iPad securely. Mine popped out, bounced off my child's car seat, and out the door onto concrete. I now have a large diagonal crack on my screen.
Apple's warranty does not cover physical damage, and my credit-card protection was valid for 3 months, and expired 15 days before this 'accident'.
So I can't recommend this product to anyone, unless they like living dangerously and have lots of insurance.
