A:AnswerI never looked at my model number and it worked. You can bring your ipad in store and try it. It isn't plastic wrapped. Just open it up and try it out. I have a model MR7J2LL/A
Just make sure it's compatible with your buttons. It also says on the box whether or not it's compatible.
A:AnswerYes, it fits mine. Although, there is a noticeable gap behind the iPad and the back of the case. The iPad is still held firmly in place though.
A:AnswerI would be inclined to describe the case more as heavy rather than “bulky”. It does provide substantial but heavy protection when closed. The pad and keyboard can be maintained intact - opening “together”, or can be easily separated. But when separated there is nothing to cover and protect the iPad screen.
