USB stick has initially worked flawlessly in a car radio. After only 6 months came first dropouts so that it could be soon no longer be written and formatted correctly. Submitted to Intenso with the request for replacement under warranty. The (uninsured) parcel was lost, investigation request the post office remained inconclusive. Double annoying. Prefer to invest few cents more in the "Kingston DataTraveler Micro DTMCK 16GB". The works perfectly so far and can be described quickly.
