Product gets 5 star has now survived 8 long day trips. Very good transmission power. Even if in the background a faint transmitter is therefore the frequency gewähte not completely clean, it overrides this reliably without much noise. The remote control does not respond optimally because it must be held directly in front of the machine but otherwise no detectable problems. MicroSD card I have so far tried an 8GB without any problems. USB flash drives I have so far only 2 and 4 GB tries which still corresponds to the description. Normal SD card I have tested 2GB. Unfortunately, I have no greater MicroSD card at the moment 8 GB is the largest that I have at the moment. The sound is good and the basses come across well. I can only recommend this FM transmitter. Because of their transmission power it disturbs not especially if the cigarette is something farther away from the radio. I already had other devices where a distance of only one meter has already influenced the reception and Stöhr noise or oversteer of radio stations in the neighboring frequency range were the result.
My conclusion thumbs up. The only slight criticism is and remains in such devices are extremely cheap remote control. If this off then you should no longer sort the music files on the storage media in folders because then the change between folders is difficult. Anyway I draw from no stars for this transmitter is the best I had so far in this price range in his hands.
