This is the review of the QJ Pillowed 4×4 and 5×5. These cubes are pretty decent but sometimes the pillowed shape can interfere when you’re speed solving.
The 4×4 is pretty good but uses the Rubik’s mechanism and doesn’t corner cut that well. It’s more of a collectors item than a speed cube.
The 5×5 is also pretty smooth but again it uses the old Rubik’s mechanism so it sometimes catches and also doesn’t corner cut that well.
