It will be good to list which specific click variant (Tactile (MX6C-T3NB) or Click (MX6C-K3NB)) each one of the off-the-shelf keyboards and the Dell module have. Can be useful for someone that wants to buy some of these keyboards without testing it, or wants to know which specific switch he tested when trying some of these keyboards. Also list if there are variants of these keyboards/modules with different switch variants.
