I have a TM680 Mechanical Keyboard that has been customized for sale. The keyboard has an upgraded metal golden volume wheel. There is a large amount of foam throughout the keyboard to reduce vibration and make everything sound better. The switches have been lubbed and the more the keyboard is used should allow them to sound even better. The keyboard is bluetooth and can also be used with the type c cable directly connected to pc.
