On the whole, for the price OK. Have the device is connected, set the radio frequency, inserted SD card and the music could be heard immediately. I needed for a single minute. Have the device tested on different radios, the sound sometimes good, sometimes less good. Is probably also related to the quality of the radio. The bass could come out a little better. Otherwise, operation is simple and yet reliable.
