I started this thread when giving more thought to the opinions that old furnaces were reliable, easy to fix, and newer furnaces are the opposite. In one example of that, I replaced my old furnace with a new one about ten years ago. The fucking thing is so unreliable that I've got spares for the main components and stand ready for the next time of distress
With that said, what have you got that's been bullet proof? My examples:
1) A 10 year old Yard Works lawnmower with a Briggs & Stratton engine. My front lawn is typical size, but the back yard is 80 by 80 so it's getting a lot more wear and tear than a typical yard. Thing is, in all of that use, I've only replaced the plug once, and cleaned the air filter about 3 times. But even than, I didn't do it because the engine was running rough, but rather more of an offering to the engine gods.
2) My Shop Vac. Nothing more needs to be said about that.
3) My USB sticks. As a computer tech, I have 1 or more in my pockets at all times. Dropping them or putting them the washer has no ill effect, but it does it when answering the proverbial question of, "Is that a gun in your pocket, or are you just glad to see me".
4) My 78 Caprice Classic or 88 (Suzuki?) Sprint.
That's it for now. Yours?
