I was due to a small accident (Cola on keyboard: D) forced me to order a new keyboard so I chose the Apex. Despite that I had concerns because some recessions negative descriptions in terms of the functionality of the keys contained, but I have had different experiences. So from my side there is nothing to complain about, lighting 1A Super keys that are very satisfactory from the feeling of pressure, processing makes a qualitative impression and 2 additional USB are also very useful.
