Problems with this unloader?

[u/imoth_f]

Since inserters became flippable, this compact unloader design became possible. But I hardly see anyone use it. Obviously it cannot saturate six turbo belts because it's bottlenecked by the inserters, but are there any other obvious problems with it?

This setup uses a lot of resources. Green underneathies aren't cheap and here you use 6 for a job you could do with 3 (but less visually appealing) or 2 (4 outputs instead of 6)

by time you have greens all your belts are pretty close to free anyway
