I am a MA and I have been perplexed about the droid repair tool.
How do you use it, everytime I use it, there is a message that
no weapons are in need of repair.
Weapons, from a Droid repair tool?
I have read on this board that some people have seen results with this,
Please reply what results and how, or is this another Nemodian Bird Cage.

BTW- the nemodian bird cage has become a catch phrase in my office when things have no apparent use and is basicallly a waste of time and money.
