I have been content with Zeppelin for two and a half years already. Yes, in fact, after six months of service, something happens to the power supply, it does not work and the red light starts blinking. But I did not carry it to the "official" service center at the River Station, because it is very expensive there! 7,000 thousand for the repair of a power supply unit, which is a year and a half old and whose price was 30,000 is pipets. I found a service center on the Internet where they made it to me in one evening for 4500. It has been working for a year. Let it be unofficial, but it is almost twice as cheap and still works.
