Made this card a few weeks in the Samsung Galaxy S2 in use. It worked at first easily and quickly. Ca 2 weeks ago the SG S2 crashed when updating an app (which was installed on the card). After reboot came the error message SD card incorrectly. Have the map then reformats and played back my (almost current) fuse. Everything seemed to work fine. Of 5 days later the same problem! Crash the phone -> Restart -> Message SD card damaged -> This time is a reformatting of the card can not be (even after several restarts the mobile phones) - tested on the PC> map, there are almost all data and apps available -> The apps and the system folder copied by PC on my old Sandisk 8GB card -> This built-in cell phone -> Since then everything works again super, unfortunately I lack 24GB memory in phone, which are urgently needed! !
Conclusion: The Komputerbay card is not suitable for the SG S2, because it always comes back to errors. In the notebook it works without problems (with transmission rates between 14MB and 17MB). I would have just used for Galaxy, therefore only 2 stars !!!!
