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 Still great, I just don’t use it anymore since I feel it’s outdated and loading speeds are better nowadays.
My nintendo DS lite. Played countless hours in it and it‘s still very good. Battery life is also still a couple of hours which is very impressive considering it‘s 15 years old.
My dslite sat untouched in a drawer for at least 4 years, booted straight up without me even having to charge it when I pulled it out. Amazing little device
