My Sony X800 M2 has given no problems. I'm wondering if the item you bought from Amazon is actually fake, and a Sony knock off. I bought my unit from Best Buy.\n\nAmazon have just announced today, they have recently found 10 billion dollars worth of fake goods being sold. I ordered Gillette razor blades during lockdown. They looked genuine, but they were rough and lost their edge almost right away. I'm sure they were knock offs.\n\nWe recently bought our grandson a Mitutoyo digital Vernier caliper and micrometer for his twenty first birthday. There were numerous warnings in the Amazon reviews of worthless fake goods. So we ended up buying from a specialist engineering vendor.\n\nRight now you have to be very careful buying from Amazon. I have a hunch your player was a Sony knock off.\n\nI've been leery of Amazon for a while. Based on reviews posted by buyers, a lot of the tools on Amazon appear to be fake. \n\nI ordered a Canada Goose parka on Amazon several years ago. When I checked the shipping status, it showed that it had been shipped from China. Given that all of their parkas are made in Canada, this was suspicious (to say the least) so I cancelled it. Some T shirts I bought on Amazon a couple years ago were definitely fake.\n\nI still have a Mitutoyo dial caliper I bought about 35 years ago. It still works well. Unfortunately I sold a set of Starrett micrometers I had back in the day (I just bought a new vertical mill and the micrometers would be useful).
