While switching the chipset isn't ideal (for an imaged environment), Kingston should at least have used a different model identifier... i.e. /a, /b, or so on.
However that is different to what many SSD manufacturers are doing now which is nothing other than scumbag bait-and-switch - release a product, get good reviews, replace the product with something cheaper and inferior.
I get replacing chips and so on, after a product release, and particularly these days with the supply issues - but replacing chips and supplying a product that is inferior to the original is dishonest.
Some laptop manufacturers also keep the same model number while seemingly changing the components weekly.
