My iPad Otterbox Defender case cracked in two spots and was unusable. Having had it for some time, I sent an email to their tech support and asked them to mail me replacements and I would be glad to pay for them. Instead, they sent me an entire new case at no charge, even the shipping was free. And WOW - the latest generation iPad case is light years ahead of the one I had broken. They really refined their design and the new model is far superior. This is a great company, they went above and beyond the call of duty as I was really just looking to order some parts.

Highly recommended, not only for their customer service but for the product itself - it WILL save your iPad if you drop it (ask me how I painfully know), and the integrated stand is so much better than the one on the Apple Smart Cover. If you have a naked iPad and you carry it anywhere at all - you need an Otterbox unless you want to buy a new one when you drop it.
