This article will no doubt be greeted with the normal spectrum from applause to ridicule.
Personally I feel inclined to identify with both.
At the ridiculous end of the spectrum is extraordinary the lengths that a manufacturer will go to for a relatively small improvement.
At the other end of the spectrum I applaud the effort … for the same reason.
The article is written by Ben Champion who, pardon me, championed the cause of better group head parts at Decent Espresso.
