I have an ASTKB102, which if I remember correctly uses a Keytronic capacitive setup. Given the potential on offer with capacitive switching, and the expense of having it, it's very disappointing.
In addition to a shaft moved by the keycap, there was also a loose rubber dome that sits between it and the keycap. I can only hope that this has decayed over the years and lost some springiness, because the keys very little resistance. As for feedback, there was some travel on offer, so bottoming out's your feedback. And as bonus feedback, you might get characters on your monitor.
Besides the switching, there were other signs of grand ideas; heavy block-like construction, substantial risers with a very tense spring holding them down, two-shot keycaps, and shiny silver AST logo. So, considering the potential from the effort made, it is the worst thing actually to type on I possess. But yeah, the age could have something to do with it, so perhaps this is inadmissible.
