Metal mousepads are fine for wireless mice.

Usually. The tracking sensor (optical or laser) doesn’t care about the surface material—it’s reading the texture, not the conductivity. The wireless signal is a separate issue, but modern mice are designed to work on all sorts of desks, including metal ones.

If you’re using a high-end gaming mouse or a Logitech MX series, you won’t notice any difference. The antenna placement inside the mouse is usually on the top or sides, so the metal pad doesn’t block much. Problems only crop up with really cheap mice that have poorly shielded radios, or if the pad is unusually thick and creates a physical gap that messes with the sensor’s focus distance.

I’ve used an aluminum pad for years with zero issues. You’ll have more trouble with glass surfaces than metal ones.

Don’t overthink it. Just check the return policy if you’re paranoid.
