Bests & Worsts Reviews from Amazon

UPDATE of 1/6/2020: In addition to selling product that is not quite as advertised (and perhaps not safe for certain applications), this company is manipulating the star rating for this product by bribing people into removing negative reviews. Since September, I have received 10 emails from the company offering me a "refund" of $40 for items that are selling for $27 if I will just remove the review (original review included below). I was just going to let it go, and flagged the mail from them as spam. But lo and behold, the sender of the email keeps changing which is evading the spam filter. Look, 10 emails in 4 months is not a huge spam flood or anything, but I don't like the dishonesty of a) changing the email sender and b) rating manipulation, and c) being pestered to remove an honest and truthful review. Original Review: These outlets are a good price and work fine. However, some caution in application is necessary. First, these outlets are not UL or ETL listed. Second, though advertised as 15A (which is also printed on the back of each unit), they are apparently not capable of even 12A continuous in 70F ambient (see attached picture). A level 1 EV charger was plugged into this unit, and you can see how it's melted. The EV manufacturer requires only a 15A circuit for the charger, and I have never seen the charger draw more than between 11 and 12 amps (whether measured by this unit or a kill-a-watt). So it works fine, but not at 15A.... something UL/ETL testing surely would have discovered if the units had been submitted for cert.
