I like this tool for "re-mooning":

It also works well for "de-mooning" but I prefer this tool for that:

NOTE: The first tool will both re-moon and de-moon cases. The second tool will only de-moon but does two at a time in 2.5-3.0 seconds per clip.

I have and use both.

For range use, I use Auto Rim cases or if using ACP cases use the polymer RIMZ clips which can EASILY be done with only the fingers.
