Essentially, the Aerox 9 Wireless is the MMO edition of the Aerox 5 Wireless. The shape is the same, but the left side has received the usual 12-button layout. The TrueMove Air sensor, TTC Golden Micro main button switches rated for 80 million clicks, and pure PTFE feet have been kept as well, along with 2.4 GHz and Bluetooth connectivity.
