Apps Quick question: Is it worth removing AdMob test devices before releasing app?

[RED_]

Didn't really want to start a new thread for what is a quick question but there's no real place to stick it.

Do you think it's necessary to remove the test devices I've declared in my XML before releasing my app? I mean surely it only effects the devices I have listed..? So basically my devices.

Like I said I declared my test devices in the XML using ads:testDevices=""

Thanks for the help.
