Power button did not work properly, it smells burnt and much more ... The device is not usable. - Quality control there seems to be no in this company. Again, the unit must be returned. But this time we demand the money back. The device is not cheap and a pile of junk, a merchant means a lot of trouble and inconvenience. Let's see if we get the money back at least without problems.
