Value for money nothing to say, it does exactly what is expected of him. Easy to use swimming as much as on the PC (for transferring files). The battery holds up well distance. I swam for 2 hours and did not weaken. Moreover the reader is easy to hang the glasses thanks to its clamp that holds very well surprisingly enough even upside down. I personally recommend as though some say the above plugs headphones comments hurt a bit the ear canals of the ears and the earphones let in a little water. But for me it is not a problem, I will continue to use it
