I’m not sure how I found this product but their review page is very odd. Seems like some strange behavior. First, their reviews are comprised of a ton of video reviews, more than most products and all seem really forced. – https://www.amazon.com/gp/product/B01JQROZZS/ref=ask_ql_qh_dp_hza
Then there’s this question: Are there any internet reviews of Portal? with a handful of answers with links all within a day of the question.
It’s just an odd Amazon page overall.
