I've bought the Mumbi-Flipcase for my new Samsung Galaxy S4. Admittedly, for 11,90 Euro I have no premium product expected. After fast delivery but then the surprise: I received a well-made case with clean seams. The high-quality impression was reinforced by tailor-made support for the cell phone. The Case has openings for camera, flash, speakers and charging port. The closing magnet holds perfectly. The mobile phone can be charged in sealed envelope. My Review: well-designed case, can not be beat in price-performance ratio.
