that's simply not true. i have mould king bricks that are indistinguishable in quality from lego. and many other brands as well. i have been buying other brands in china and i haven't seen a difference in quality for about a decade or so. the last issue i remember reading about was that some factory produced bricks with varying tolerances depending on the season, because the factories were not climate controlled. and that story is already several years old.

so yes, you could have an old set from a bad charge. but the times where lego was guaranteed to be better are gone.

For a child most sets will be fine if you don't need to care about the price. Though some sets want to install an Smartphone app for full functionality which I think is a pretty shite idea as most good parents want to get their children away from the screens.

However a lot of adults are also collecting Lego. And the 1000 Dollar Death Start is aimed at them, not children. It is an UCS set, which normally means higher quality.

The problem is that a lot of cost cutting measures have been used to save up a few cents here and there for the most expensive set ever. The figurines are trash. The sets includes stickers. The problem with stickers is that they look like ass over time so not really suited for serious collecting.

The backside of the set looks absolutely disgusting. Which would be fine as you could put it in front of a wall but alas you can only access certain features by the backside. The elevator mechanic is trash. Honestly just watch a video of the thing.

And worst of all, the Tie Fighter needed for the set to be complete was only available as an extra goodie for early buyers to spread FOMO. One thousand dollars and you don't even get the whole thing. Scalpers sell that Tie Fighter for like two hundred.
