I don't use them with mine. I have them on my cheap quadcopter that i fly around the house and it has saved me a lot when crashing into walls and ceilings and such. but i only fly my phantom outside so i have not had a need for them.
i also don't like them because they affect performance. i'm afraid of a heavy wind day when i forget to take them off and find that even in ATTI mode i can't control my copter enough to bring it home...
