Ejector Upgrade (IndustrialCraft 2)

An Ejector Upgrade is one of the most useful upgrades for machines in IC2. It automatically output products to the first available inventory.

Usage
Place this upgrade in special slot for it. Which mostly is on right side of gui. (If you can't find it, just shift-click on it with open machine gui)

Configuration
But sometimes there's more than one vailid inventory next to the machine with Ejector Upgrade. So, what you can do? There's reason for it. You must have an Ejector Upgrade in your hand and click on the opposite side to side where you want to send items. Now, Ejector Upgrade is configurated and it'll send items to only one side.
