After a week of testing, I am convinced by this product. The sound generated is not the richest but FM transmission is fairly good. The device is finally small enough and simple to use, even if he wants to do a little too much at risk to make complex manipulations. By staying basic, the device does very well the job. The question is whether the reliability will make the perfect product. It replaces the New potato Tunelink who had not taken in time. The Jabra, anyway, actually more for less. I recommend.
