Total disappointment! As a sports swimmer I wanted to bring a little variety in the desolate tile counting. The first copy was not switched on and was replaced by Amazon easily. Although the replacement model worked, but the music is so quiet that you can swim in sports (Kraul) can not be heard because of the breathing and flow noise. In addition, I could also use the smallest essays listeners do not get into the ear so that they considered reasonable. When powerful thrust from the water's edge, the device slipped so easily. Have returned then the device.
