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 Still great, I just don’t use it anymore since I feel it’s outdated and loading speeds are better nowadays.

Sometimes yes, sometimes no
Unless you have to refill their ozone-killing stuff for them to work properly.
