Fitted with rubber rings all Keyboard is quieter, but felt the buttons are now sluggish, with some keys I had the rings probably not far enough hineingedrückkt, so the key was no longer really trigger, here had excessive keystrokes help the rings in position bring to.
The Tastenkappenabzieher I have often used, but would have a device with desired dezenterem construction. Between the buttons on the rim of the Puller has poor fit in, or I was too cautious.
For keys with other materials such as Shift, Caps Lock and enter the puller was not to be used.
I'll be watching the matter and possibly late filing an update in a few weeks / months.
