There used to be good warranty support - 10 years warranty. Therefore, the spoiled cards (read lock) were changed about once a year under warranty (some as many as 3 times). A year ago, the warranty period was reduced to 2 years. And now the warranty exchange does NOT WORK at all! (for example, my current RMA RX2068303 - they have been feeding "breakfasts" for a month and hanging all sorts of nonsense on their ears)
