Honestly, they fail more than you'd think. My buddy in the trade says he replaces springs way more often than the openers themselves.

My buddy bought a fancy French press and was boiling water in a regular pot for weeks. He'd complain the coffee tasted weak. Turns out he never read the part about needing to actually put the grounds in the top chamber, he was just pouring hot water over the empty filter. The look on his face when I made a cup correctly was priceless.

Stick with the grease the machine was designed for. That new synthetic stuff just doesn't have the right body for worn-in parts. You learned the hard way, but now you know.

Pete's old gear locker was full of weird surprises.

Practical tools win every time. My garage is full of fancy gadgets that looked cool in the store but just collect dust. The simple hammer and screwdriver get used weekly. People get sold on features they'll never actually need. It's a marketing trick to make you spend more money.
