To be fair, I have seen a few machines that do lose their time quite easily - they've all been the Costco/Walmart level fairly new machines though and it's not specific to those 2 brands either.
On a vintage machine, it's rare to throw the time, I agree. With the newer low budget machines, their needlebars are softer than the needle sometimes and the way the hook drive mechanism is built, you get one try then the nylon has flexed too much to be strong enough anymore and the machine is garbage.
I don't consider the people who believe the OSMG to be stupid. Trusting to a fault maybe but if everyone could service their own machines, there'd be no bargain machines out there and not a lot of opportunity for people like me to do something other than IT.
