Glass mousepads vs cloth mousepads: Glass wears down PTFE feet much faster than cloth

Glass pads grind PTFE feet down in 2–4 months vs 6–12 months on cloth, because glass is hard and microscopically rough while cloth is forgiving. The trade-off is worth it if you value consistent glide and easy cleaning, but you’ll need to replace feet regularly. Stick with cloth if you don’t want to stock up on replacement feet.
