I recently purchased the same item. It worked well. In fact, I had purchased an even more expensive unit. But when I received my CaseCrown unit I compared the two. I put away the more the more expensive unit and opted to use the CaseCrown product.
I think the iPad4 is the same dementions so the only question is where the cutouts are. There is one on the middle of one side for the on tab, another on the bottom right for the volume, middle right and top right.
Yes, I bought it for my iPad 4. It is perfect. It has all the correct openings for the features on your iPad. Holes for speakers, openings for power switch and volume switch. Arched grooves for the home button and the Skype viewer (camera). On the back of the cover it has a cut out for your camera lens. Hope this information helps!
