It was urgently necessary to fix the tablet, which was constantly rebooting and slowing down at every step. I called this service, the master said that he could take the device on the same day and perform a free check. A couple of hours later, I was told that the software part was malfunctioning and needed flashing. The price for the work seemed quite normal to me, so I agreed. Before the evening, the tablet was working again, as in the first days after purchase. The guarantee gives you confidence that the problem will not return unexpectedly. Thanks for the quick decision!
