I don't know why so many people say that the fop clip is so hard to install. If you do it carefully you can have that thing on and off in a matter of seconds. I like to use a crosshead screwdriver, and just apply pressure on the clip, instead of that flat plate where you can use a flathead screw driver. I place the crosshead screw driver in between the blades of the fan, and from there place it on the clip and apply pressure, and before you know it, it is on.
