To be generous, you were suckered by marketing.

To be less charitable, it was partly your fault for having blind faith in branding.

If you want a stockpot just get a good stainless one from a manufacturer that makes good stainless.

Something that is widespread in consumer space is a company that has a deservedly strong brand in particular space deciding they can cash in on that brand in another space. As an example, Ridgid make great pipe cutters but there is no way I am buying their random power tools.

As a consumer, you may wish to educate yourself on this effect and be more critical going forwards.

This item from Le Creuset is transparently them cashing in on their name and style for enameled cast iron and trying to extend it to other random crap.

If Le Creuset came out with a vibrating butt plug next week, would you buy it? I suspect not. But you just did. This is roughly as related to their reputation for enameled cast iron as vibrating butt plugs are.

So why the fuck would you buy a pot made of thin sheet metal dressed up to look liked enameled cast iron but clearly a bunch of crap?

The power of marketing and branding.
