I do, prior to using the 4000&#x27;s I was using mechanicals for a significant period of time (back to Model M&#x27;s).<p>Yeah the key-feel on the 4000 isn&#x27;t as good as a MX Blue or equiv but it&#x27;s not significant enough to actually matter and in every other way they are a more comfortable experience.<p>The ErgoDox costs at least 5 times what a 4000 does so I&#x27;m not sure that&#x27;s a fair comparison you are comparing a VW Polo to a Audi A7.
