This is an excellent case that I believe is better than Apple's, for significantly less money. If you need an Apple logo then this isn't for you; otherwise it's great. We are a two iPad family (one received as a gift) and actually have both cases, so it is easy to compare. The iPad slides in easily and is held by a strong frame along one of the long edges and two corner "loops" along the other long edge. The fit is very tight and secure. Sliding the edge with the volume controls into the frame results in no loss of any button functionality (one reviewer mentioned that the volume buttons are partially blocked--that's only if you put it in the other way). Our Apple case actually partially blocks the speaker, although my guess is that some do and some don't given manufacturing tolerances, but regardless, the Acase fit is actually better in our experience.
What makes this case particularly good are three features: 1) the case is slightly cushioned. While it makes it slightly thicker than Apple's (1/8th of an inch), in my opinion it also makes it more protective and reduces the "worry factor". 2) it has four different "blocks" that you can rest the side containing the iPad in to create different landscape viewing angles. These are sturdy and offer more flexibility than Apple's design. The lowest setting does not get as low as the Apple case's "typing mode" but I find I rarely use that anyway. 3) it has a loop that snaps the halves closed. This seems trivial but if you are putting it in a carry-on or purse, it provides more protection against things getting between the flaps and damaging the screen. Apple's just folds closed with nothing to secure it in that position.
Other reviews have cited that it isn't real leather. Honestly it's hard to tell but whatever it is made of, it is high quality and pleasant to hold. Apple's isn't leather either, rather it is a matte rubber type material. One disadvantage is that the edges are not as protected with this case vs. Apple's (the Apple case is a frame on all 3 exposed sides) although my principal concern is the screen, and so this is minor in my opinion. Also, obviously the buttons, speaker, etc. are exposed with the Apple case and those are what is at risk along the edges anyway.
I gave my wife the choice between this one and Apple's, and after trying both she went with this one. I would have as well. Overall this is an excellent case.
