I bought this case in Feb and it's fine up to 6.1.3. In ios 7 this case doesn't allow you to use control centre because it swipes up from the bottom and with this case you can't do that. so if you are using a pre ios 7 device this is fine.
I'm looking for a new case because i cannot use control centre anymore!
I was suggested this book on my uni reading list. I bought it and it was far better than the other physics book I spent a fortune on! The concepts are well explained and laid out. There are lots of nice questions to test your knowledge and very useful summaries throughout. If you could get any one book for university physics, this should definitely be one of them!
The item worked intermittently. It worked in some orientations and not in others. I tried with 3 different batteries and the problem persisted. I must have been extremely unlucky and had a faulty item but I don't have the patience for a replacement and requested a refund from Amazon.
