Dimension is just one thing. Materials is another. You can give me a 100% in spec lower for example that’s been 3D printed with a polymer..It’s junk compacted to an in spec made out of 7075.This is a different statement than "they're all the same."
No, if every dimension is out of spec, it's not a deal. It's just cheap.
All the garbage components don’t get so cheap because the manufacturer wants to give you a deal. There were corners cut.
