Compared to the comments already posted on the article, I was skeptical but I tried it and I'm really not disappointed !! At the qualities of the device itself, are very satisfactory, simply read the instructions carefully to understand its operation, including energy saving, a default regularly pointed finger in the comments. A simple copy and paste enough to put music (I have tested it for now).
The only real downside that must be noted is the fragility of the loop of the bracelet, you have to be very careful if it breaks, what happened to me. ^^ This is why I take a star.
