After a month of playing RDR2, it hasn’t given me any problems, even with heavy use.
I had several 1–2-second black screen flashes, which stopped after I replaced the HDMI cable with the one that came with the console.
The console arrived very well packaged and was in the condition described.
The only two downsides: the controller isn’t an original Sony one (the one included works fine, but I would have liked to know), and this model has a very noisy fan.
