Excuse my blatant asking but is there any consumer protection in US and CA?

Like this:

Under EU rules, a seller must repair, replace, or give you a full or partial refund if something you buy turns out to be faulty or doesn’t look or work as advertised. You always have the right to a minimum 2-year guarantee, at no cost. However, national rules in your country may give you extra protection.
You can return any purchase within 14 days without justification...

This actually pretty old law served me well as 14d are usually enough to test a drive quite thoroughly (including badblocks).
