Yes, 'clicky' is a subjective term, but likely the seller knew precisely what they were doing by placing the word 'clicky' in the description.
No, "clicky" is
not a subjective term. It is a distinct feature of some keyboard switches. The term is used by
respected keyboard manufacturers such as Cherry, Alps, Unicomp, Matias, etc.
A "click" manifests itself in a "click" sound that coincides with tactile response and the activation of the keyboard switch.
I see that you don't have many posts here, and are looking for a Model M. Once you have one, you will know the difference.
Some sellers have confused clickiness with the sound that occurs when you bottom out and there is no dampening. That is fine, that is just ignorance. However, I have seen other sellers on eBay sell keyboards that I know are mushy rubber domes, where they can not claim ignorance.
If enough negative feedback is left, eventually people will stop buying.
Many of these sellers sell a whole lot of other stuff, for which they get positive feedback. Once they have enough number of positive sales, one person giving negative feedback is like peeing in the ocean to their reputation.
And yet, the information is out there about keyboards. If the product images show a label, research the hell out of it.
Not always. There are many good vintage keyboards out there that are not well known.
There is one clicky keyboard that I bought on an auction site. The brand was unusual and a Google search for the brand resulted in no hits
at all. It was new in box, with product leaflet, but there was no name of the manufacturer, no model number and no FCC ID anywhere - not on the box, the label, keyboard, not even inside the keyboard anywhere. I suspect that it was made by Chicony in Taiwan, but I can't tell for certain.
I bought it because the seller was cooperative, told me that it was clicky and sent me a picture of a key with the key cap off revealing something that looked like Cherry MX.
