have bought the item in spite of the contradictory reviews and now since about 4 weeks in use. Immediately after unpacking I had it loaded which lasted with a 1.2GHz Android tablet about 40 minutes about 18 GB of music. In my BMW, it took until the stick is read no 30 seconds works since then without any problems or interruptions, the stick is always recognized (its predecessor, 16GB NoName, unfortunately not). Conclusion: For the intended use ideal! (Automotive USB)
