To further shoot holes in that argument, if you buy a Leviton (name brand) product at HomeDepot (name brand store), the chance that it's counterfit is virtually zero. The bizarre argument he's making is that because name brands can be counterfitted, it's pointless to buy a name brand anything. Seems to me buying a name brand product through a reputable channel is the best practical way to be sure you're not buying some defective knock off. What's his solution? Buy some from wherever and send them out for analysis? A lot of these kinds of products you couldn't even take them apart to see what's inside without destroying them, and even then unless you're a tech expert you still wouldn't know what you have.
