Horror, horror, horror. Refilled the cartridge once - I had to buy a new one. The headphones and webcam did not live up to the end of their warranty period. Out of fright, I also bought a tablet there - and was left without a tablet. Contrary to all the laws on warranty service, they tried to repair it, it didn't work out, and they shoved it back to me with the verdict that it was "broken". In another service center, it was proved that the tablet is not broken, but only scratched. There were traces of attempts to repair it inside. Draw conclusions about whether you need to contact such a store. Their warranty obligations are worthless!
