I have an unnamed non-magnetic YJ cube that I bought for $3.90 from a mall and it's turning feels more like a $10 budget cube from 2018. I have never seen a core of a 3x3 like that before and the cube is non-adjustable (no screws).

The cube itself

Side by side with the super rs3m ballcore (left)

Core

Center cap off

Spring and piece removed from center; underside of center cap

The packaging of the cube looked like this (it was wrapped in plastic without a box and the model name was not shown on the price tag. Note that the YJ on top is not the same exact model as the other one and they were bought from two seperate stores)
