Upon joining, I immediately had the idea for a great feature we could have: Mean Failure Rate
This would be an invaluable metric when considering buying some piece of gear, whether vintage or quite new.
Simply put, if you have had a piece of gear break on you, you could mark it as "Failed" or "Broken". And for further details, I think another good option for this metric would be whether it broke within the warranty period, or after it. To push it, maybe even how many years after manufacturing it broke.
Status: [ Broken ]
During warranty: ( ) yes ( ) no
Years after manufacturing: [ 5 years ]
Where [ ] denotes a dropdown menu, and () obviously a selection.
This is a great idea.
Maybe connect it with a gear rating system.
