This mumbi Case (mumbi Premium Genuine Leather Flip Case Samsung Galaxy Ace 2 Case) first made a very good impression. However, after about 3 months, both the magnet on the hard plastic cover have left, as well as two of the four retaining corners (both lower) canceled. There's probably happened because you the hard plastic shell can bend almost before it breaks. The phone's keys could be good in the shell use and were not covered by the sheath. The mobile phone fitted well in the casing in, but when the phone was once "snapped", so it was very difficult to get it out again from the casing to clean it for example.
