About the question: How does it behave after a year or two?
The old days with the massive hand soldering, you was have more reasons to worry,
than today that robots do all the work at very specific conditions.
Even the quality of the solder wire is very specific.
....
Yeah, robots are nice, but even they make mistakes. I also think that vibrations and thermal stress are things that may affect your dmm. Another part is the LCD......is it still nice and crisp or does it start to fade and loose contrast (could be often handled with just cleaning the contacts), but even more:
From time to time you may encounter new problems to solve. I don't think you buy a top-end dmm or lcr-meter and use it's functions right on top. Normally you test the ground functions and they work (should be), but there may be hidden issues like the Fluke 287/289 logging bug with the incoming light through the IR connection. The more you use a tool, the more you find it's advantages and step on disadvantages

That doens't help a potential buyer if you never update a review......that's what I mean.
