This is my second case, this one bought for my mum in law. It's a good product for the price and it protects the iPad well, but this second version differs in design from my previous case and because of the solid microphone cutout to the reverse, the case turns your iPad off when you fold the front cover behind the back cover. On the previous version this is not a problem because the microphone area is perforated.
You can avoid this by not folding the front cover behind, but it can be annoying. That said she is managing with it but had it been a more expensive case we would have returned it.
