Mine… My Xbox 360 slim only costed 129 euro back in 2012 and to this day still work like brand new, you would think that the disc drive would stop working but no. Never had the need of open it or clean it’s insides. Still great, I just don’t use it anymore since I feel it’s outdated and loading speeds are better nowadays.
It’s definitely worth it. Since you game on PC, you already have a library of games for it, and steam sales frequently let you get games for pennies on the dollar.
