Flip the mouse's power switch into the OFF position, unplug any cables, and flip it over so the feet are facing up.

The unique shape of some mice can prevent them from laying flat. If you need to, lay your mouse on a soft towel to prevent wobble.

If you're planning to reuse your existing mouse feet, note that the adhesive needs to be thoroughly heated for them to be cleanly removed.

Heat an iOpener and apply it to the mouse feet for about two minutes.

Alternatively, you can use a hair dryer to soften the mouse feet adhesive.

When using a hair dryer, don't heat the feet for more than a couple seconds at a time—anything hotter than just warm to the touch risks melting or warping the plastic lower case.
