"Also, some Chinese sellers will flat-out lie in the specs, so when you're a cheapskate like me, buy from a marketplace that offers hassle-free refunds." This is the takeaway. Some lie about it knowingly, and some just don't know any better as they are just reselling devices they bought in bulk from the manufacturer who lied about the specs. This mode of operation is systematic with cheap Chinese products and the sales of such, because every time one of those few alert customers bother themselves with raising the issue, the seller instantly negotiates a discount - now they still made a buck and you still accepted to pay for a faulty product, because it's less hassle than returning it, and shipping it back often costs more than the device itself. Whenever I pick up some cheap Chinese trinket I understand it will be a gamble.
