THE BIT THEY DIDN'T PUT ON THE BOX.
A mouse got expensive shoes.
Esports accessory brands sell precut replacement PTFE (Teflon) mouse feet for £10–£15 a pack. A single roll of industrial-grade 3M adhesive PTFE slick tape costs £12 and contains enough raw material to cut thousands of identical mouse gliders manually for pennies.
SO WHAT'S THE CATCH?
Tape is raw material: cutting, adhesive specification and thickness matter.

Look for complete part numbers and revisions, make sure you're comparing the same quantity, and check the exact model/application. That's especially important with electrical, braking, steering, battery and other safety-related components.
