Even if I decide to retain this product, I am not satisfied with the description given on Amazon because it is mentioned in the "diet: NO". I was expecting to have a self-powered hard disk. And I discovered on Christmas Day by offering it to my daughter that there was food, which makes them less easy manipulation hence my disappointment. Regarding the product itself, there is nothing to say, it is good, if the description had been different, the product would have merited between 4 and 5 stars
