After a few weeks of use another short review of the pdair aluminium case.
I found that the case has a few annoying "features".

* the top cover doesn' t sit tightly so when opening the cover the screen is usually covered in lint from my pocket
* the top cover prevents the use of gestures from off screen to on screen e.g microb's back and cursor select.
* as people have stated before. The static closing clip can hit the screen if not careful.
* it is bulky

Bottom line is that I probably wouldn't buy it again even though I have a two year old who likes to "handle" the phone.
