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 Still great, I just don’t use it anymore since I feel it’s outdated and loading speeds are better nowadays.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 first Chromecast i bought years ago for 20$. It’s still faster than the Google TV with a remote and I quite like to use my phone as a remote.
LTT screwdriver - although quite expensive has been a great tool when moving a few times, and for everything really.
An old receiver I got used, for 30$ has been with me for 5 years now, and it’s sadly starting to misbehave, but I can’t afford a new one ATM so I’ll suffer through it as it powers everything I throw at it with ease.
