Calf stretcher for $50. It cures my plantar fasciitis allowing me to work out, allowing me to not be depressed, allowing me to stay alive.

recently? hawkins 3L stovetop pressure cooker - I use it at least twice a week, mostly with beans, rice, root vegetables. been using for about 18 months. no issues whatsoever.

historically?

• ecco shoes, the pair I had for 9 years just wore out last week so I decided to try a different brand.
• filson coat (double mackinaw), it's a beast, but I only wear it 5 months out of the year - in the late fall/winter/early spring
• hp 9480m laptop, have had it for 10 years now, daily use, had no issues at all. no changes, other than updating it to win10 5 or 6 years ago
• all-clad steel cookware (pots/pans/skillets), had the set for around 15 years, works really well.
• futon mattress, custom made, 6' wide, 7' long, 6" thick, had it for 20 years now. super comfortable

just about everything else wears out, breaks, or in the case of most electronics, has planned obsolescence built in after 3 or 4 years.

My 2018 15-inch MacBook Pro. It's both the best (and worst) purchase I've ever made.

On one hand - that thing is the reason I got into working in creative jobs (3D, video editing, etc). On the other hand - it's the worst computer I've ever owned. I've had it for the past 4 years and I'm already planning on replacing it next month.

A BMW 650i.

Judging by the answers, nobody’s heard of global warming, overshooting planetary limits, etc. Oh well…

Bitcoin. It'll pay off in the long run, trust me.
