[EX Q]: As someone who uses her ipad quite frequently, I needed a case that would offer a durable protection with flexibility to suit whatever need I had. After looking for quite some time, I have found this case which has made me very happy. The instructions are clear, the product feels very solid, and I am relieved to find a case that all my needs. Typing has been easy and I am very happy with my purchase.

positive
