Given that this is half the price of Twelve South's bookbook case for iPhone 5, I expected to get a cheap imitation here.
I think it's fair to say this IS a Twelve South imitation, but it's a close copy of their iPhone 4/4S bookbook style of case, not their iPhone 5 bookbook case. (The new Twelve South iPhone 5 bookbook case has a clip to secure the iPhone 5, rather than sliding the phone into the leather holster and securing with the tab at the top.) Personally, I loved the Twelve-South's bookbook case for iPhone 4/4S, but didn't like the new Twelve-South bookbook case for iPhone 5 and I returned mine - it looked cheaply made, it was an extremely tight, awkward fit getting the phone into the clip and the case had large remnants of glue coming out of the over-sized piece of plastic they decided to stick in the (rather enormous) hole they cut for the camera. This product is better quality than the Twelve South product. It certainly looks and feels like real leather, although I suspect it may not be (based on its smell). If it turns out to be imitation leather, that would just be a bonus for me, because I'm mostly vegetarian anyway :-) If this were the same price as the Twelve South bookbook case for iPhone 5, I would still prefer this BoxWave case.
