Nothing to say, it's quality stuff. It takes a little getting used to if you spend like me for the first time to a mechanical keyboard, but not after the fact, a step backwards seems unthinkable. If you are looking for excellent keyboard, and you do not need or do not see the utility functions that other keyboards offer (macros, programmable keys, back-lighting, etc) but are looking for something functional, sustainable and reactive, do not hesitate, you will not be disappointed.
