Repair Nanodrones are really neat artifacts in the game.
They allow you to repair without spending credits they are not the expensive to acquire with artifact points and you can easily get them.
I usually use them when im bashing through NPC's and the timer is running on my Neural Interface with RSL interface.
Although you can use the time manipulator instead of the repair drones. Time manupulator makes you spend your credits. that you would otherwise use for your buildings and your ship maintenance. At low levels the repair cost are really nothing and you can easily offset the repair bill with few good mining planets. but at your level goes up it becomes impossible to spend a lot on repair because the repair can be as high as multiple millions. (mine is about 10 million per full repair) when you look at it that way Repair Nanodrones are worth more than their scrap value and should be kept till you really need them or until the repair bill is really high
Just my thoughts on the Valuable Repair Nanodrones
