The value proposition of the Chinese knockoffs is off the charts IMO.

For what I spent buying JUST ( https://www.brickeconomy.com/set/60229-1/lego-city-space-roc... ) last year for my daughter,

I've since bought her a 3-floor hospital, a firehouse, a pink villa with pool, and about 2 dozen doctor and engineer minifigs for the same ~$120 outlay. Only disappointment is the legs on the Chinese minifigs, they are difficult to seat properly on studs because the legs are at a slight angle (almost like manspreading).

I have to stop myself from going on a spending spree on AliExpress, I might order an entire Age of Sail LEGO navy.

You trust the Chinese knockoffs not to leach out poison?
