Whilst not wishing to denigrate any website that promotes safety, the last mentioned date I could find on that website was 2016 and a lot of the faulty goods pictures relate to items being sold on eBay in 2011. If it is still being supported and maintained, then it needs a jolly good update with items from current and to be relevant now, the site needs to show the date it was last updated
Even if 2016 was the last (partial) update on that site, a lot can happen and change in 6 years.
I know I haven't found any issues with plug fitment into 13A sockets of the PSUs I've bought on Amazon in the past few years.
