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 Still great, I just don't use it anymore since I feel it's outdated and loading speeds are better nowadays.
The last apartment I had, the AC was old and would always go out a few times each summer. By the 3rd time, I went to the hardware store looking for a box fan, but they were out and only had an industrial fan that was more expensive, like $40. I bought it out of desperation. But looking back it's one of the best purchases I've ever made. Any time the AC went out, id whip out that metal beast and only ever put it on the first setting because the other 2 settings were way too powerful for an apartment. It's never given me any trouble over the years and has saved us from some very hot weather. If I had known then how good this fan was, I would have gladly paid more for it. It's currently being used in our house while we do renovations this summer and it's working like a charm!
It was honestly some no name brand and I wasn't able to find it on their site. But I did find this fan that's almost exactly the same: Lowes High Velocity Fan
