Blackout

We received 2 shelves and no luck for us, the two were found to have the same problem.
Spontaneously and without the battery is flat, the tablet goes out and does not restart until a few hours (if not at all, for the first). A little research on the net, it appears that this is a problem that we are not unique.

It's a shame because otherwise the tablet had it all: not too heavy, fast, fluid, useful as any good android.
But then, unfortunately, the precariousness of the battery means that we again returned it and now we turn to another choice.
