Unfortunately I am not satisfied with this product. Already after two use the function has completely failed. Even the replacement device showed the same mistake. In both devices the MP3 player went out after about 30 minutes of use, the middle of the song, and each attempt failed to bring it back into operation. The player was "dead" load, also did not go. The service at exchange went smoothly. It's a pity, because the MP3 player was a gift for my mother, who would have liked to use it while swimming.
