here is a pic of my kits , after reading your inital post it checked off all the signs to validate the kits and I ordered 4 more .Glad to hear it! Hopefully I’ll have more to add soon.
they all have the qr codes matching blue colour on the print and metal ring and space between the lot numbers and expiry less then 2 years.
inspecting 3 of the kits it shows a number of the month eg 04 rather then the month printed such as Aug , is this common or something for me to worry about ??
