What's the cheapest thing you had bought that by the end of its usefulness made you say "wow, this was worth a lot more than what I've paid for!"
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 Still great, I just don't use it anymore since I feel it's outdated and loading speeds are better nowadays.
I got an instant pot and it has completely replaced the rice cooker (I really loved) because it flat out makes better rice and it does it faster. Outside of a rice cooker costing less, there was just no other reason to keep it around from that point on.
White rice just takes a 1 to 1 ratio of rice to water, then 4 minutes at high pressure cooking and a 15 minute slow release and it's perfect. All in under 30 minutes total time.
