I am very pleased with the Flip Case. The workmanship is typical Mumbi at a high level, which means that there are this is genuine leather is (test certificate was the case with) and no seams or splices objectionable. The retaining lugs are quite tight ... the first time a little pressure must be ausgebübt insert the phone ... but that's really just so positive because the phone can not easily be removed and it sits really perfect! Otherwise, as has been written in other reviews, all of the buttons and the camera properly to use.
The only drawback for me is the weak magnetic closure. But since I already had a Mumbi-FlipCase for my iPhone 4 in which the magnet was stronger, I am assuming that this is an isolated case and therefore remains's at a 5-star rating
