Saw this on eBay France. A different version of the Buttonset (the model with colorized keys), however this one with ENTER key (instead of N/L) and with light-blue top row instead of medium-blue. Or maybe the keys are just faded
Compare with this one also with ENTER key:

I have this one in my collection:
My opinion? It is a definite positive improvement over the flat membrane, but of course no where near as nice as a full keyboard. My unit is attached with 2-sided tape which I feel may be a tad on the thick side, requiring a too-hard keypress to make positive connections
Here's photo of the Filesixty Improved keyboard in the wild. Most information is on the colorful and photogenic Filesixty Buttonset with its hard plastic keys
Not only is this marketed as improved, but all your comments indicate it is actually far better to use than the Buttonset
