The only advice I can give on this product: Avoid! I do not know if I have bad luck in the matter, the fact remains that the beast has just let go and decided to hang in the middle of reading and then hang from the start. To this is added the non-recognition by my computer and I have a useless appliance at home. I already had before we, who was quick to give us a racket to wake the dead, and I count scrupulously avoid this brand as of today (when you see the price on top of that. ..).
