Useful in storage containers if multiple different items are going in and out.
Storage should be first in - first out, but currently is first in - last out or something it happened to me that I have many different items, I placed them all in storage that was connected to "sorting" station and when I have input of different items and one item is stacking it will block other items, unless it stops receiving it. So I was missing 6 Hard drivers that were stuck somewhere. Found them by accident a few hours later.
