The speaker is good, the radio is tuned through the smartphone, it catches and works. I used a similar device from Rockbros there was a charge indication, but here it is not, and it is not clear how much the device is charged. The bike mount also looks solid. In general, I recommend it, delivery is fast, the product is of high quality.
