npub1hykucplphuhelaxutcw4jw3vuu7gcg42czhqmk7jhchs8vdga4fsj73p33 (npub1hyk…3p33) I woke up to the real danger posed by counterfeits on Amazon during the run up to the total solar eclipse in Aug. 2017, when apparently unsafe glasses were being sold there.

Amazon is not only seemingly overrun with counterfeit products with fake reviews, but they allegedly commingle inventory from different sellers who are using "Fulfillment By Amazon" (FBA) if they are ostensibly selling the same product; this would mean that you could receive a counterfeit product from seller B even when you bought from the listing of legitimate seller A if they both use FBA. After I came to understand this, I started telling anyone who would listen not to buy any product from Amazon where safety might be an issue (which it really a whole lot of products when you include things like electrical/fire safety).
