I don't think the comment about generation ahead is relevant or true.

As a final thought, I'd say at least in a store, if you have the ability to determine if something is junk by looking and touching it, you can practice that.

I'm not sure how I would tell just by looking without reviews and specs, any more than I could tell from a picture, the differences are really subtle.

The plastic cover on a bad switch looks an awful lot like the one on a good switch.

Glass filled nylon seems to be somwhat reliable thought, not quite as much utter trash has a chassis made of that, at least for tools.

And sheet metal, I usually assume anyone who uses that is cutting corners or wants to appeal to old fashioned types who hate plastic no matter what.
