Not bad ... but customer service execrable

I ordered two tablets.
First good point for delivery depending on the requirements.
After starting the tablets and navigation (activation Wifi home, reading several videos that were on the server the house, viewing multiple photos, reading several mp3 files, etc ...), nothing wrong with this product, at least for the first few days.

Then, a few weeks after normal use, one of the two tablets unbootable. After some discussion with the seller, strangely, I finally have no more news of him.

Currently I am still waiting and seller and Amazon for an exchange or refund.
