Sony 4, the device is working and does not complain of anything. I am still using it and playing heavy games on it like CoD and FIFA 27, and its temperature does not rise and it does not complain of anything. However, the disc drive, I think it is broken. I do not use discs because most games are downloaded. I bought the device a long time ago and I don't know if it has ever been opened or not, but it has been with me for about 8 years and has never been serviced except for cleaning dust. The Sony comes with a controller, but it is not original.
