edit: This keyboard line (Inductric) was later owned by Keytec. Chyrosran reviewed their DIN-ified version and did not appear to be pleased. I cleaned and lubed one of the switches on mine and i quite enjoy it; no problems with binding nor lack of smoothness. He also mentioned that his are stiff; mine are nice and light. I will clean and lube the rest of my switches to make a proper judgment, just need to figure out how to get the ferrite beads off the sliders without destroying my fingers
