I got this because it was (at the time of this review 04/18/22) the only Aliens USCM armor that was available and not priced over 50 USD.
Pro:
-Cheap
Cons:
-Only one available with reasonable price
-The up-close detailing is sadly low
-The armor pieces are not separate (they're one object)
-The leg armor does not have the back leg pieces
-In Blender, I copied and removed various pieces to make it like they're individual objects.
-Nothing in the description about the model
-Only one/"two" picture(s) showing the model, which should've been a red flag
-The armor is not well rounded. Example, the shin/leg armor has some odd shaping, the camera piece on the helmet is phased/merged through it, which would mean I have to shave off some parts or add on.
I give this a positive, because the seller/maker tried their best, and it is/was the only armor model I could find for 3d printing.
