Losing them and not holding up are two different things.
I've had mine for over 10 years so not holding up is not an issue.
You can't blame the tuner for getting lost. If they weren't stolen, then they are always in the last place YOU put them.
I haven't lost mine either.
I have a $100 that says even if you bought got another (type of) tuner you'd lose it too.
