I wanted the case but had to settle for the grip I had to adhere myself to my case. It works great and I love it, but if you chose this option make sure the placement is perfect because there is no second chance to correct. I got mine a bit too low to be really comfortable in my hand, but it works— just not as perfectly as when the wingback is already attached to a case. It would have been nice to have tips about placement.
Otherwise this is a great product. Just wish I had it placed right.
