Anyone have any experience with the Ballistic Aspira case for the iPhone 5? I brought home a Ballistic Smooth case once for the iPhone 5, but it seemed like it would be very hard to get on. The Aspira sounds like it might be a bit easier to get off and on than the Smooth while still being protective and not too huge...any opinions? Any other comments from anyone who has used the case would be appreciated, especially comparisons to the Candyshell Grip and the Tech21 Impact Mesh. Thanks!
