So 4x4 is my favorite event so I was very excited for this cube, out of the box the turning was slightly on the slower side and it felt very smooth, I then broke it it with a few solves and cleaned out all the pieces to get rid of the factory lube and replaced it with my own lube, after cleaning it out the slightly slow feeling was completely eliminated and it feels very smooth and buttery with a slight crispieness and is quite fast and has become my new main over the Moyu Aosu GTS2M
