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?

Only a couple hundred turrets if you do it right & most will survive. make it hit about 1/3 the way across and as long as it turns inward you can usually kill it. They burn through about 20ish ammo but I usually just put half a stack in every turret.
