Based on 5 reviews

This cube was insanely bad out of the box but once I broke it in it turned out to be a pretty good 4x4. This was my first 4x4 so I was super impressed. And then the pops started. It started with just one center piece pop but with that came out a white peices that helps the locking up. This happened for about two weeks until it exploded in my hands and now it is sitting in a bag. FIX YOUR CUBES YJ!!!


This cube pops so much. The center pieces will always come out so now I can barely fingertrick or to a fast algorithm without the center pieces popping.

Good for the Price

This cube turns fast and has a crunchy feel to it. So far I barely had any lockups with this cube and I got this cube in April of 2019. One thing that might deter you from buying this cube is that if you want magnets this cube doesn't have any on them. Also, this cube doesn't corner cut well and it is noisy. I would recommend this cube for beginners.

P.S. If you have the money I suggest you by the MOYU AOSU 4X4 GTS2 M because I bought this at a competition and it instantly became my new main and it still is. Here's the link to it:https://www.thecubicle.com/collections/moyu/products/moyu-aosu-4x4-gts2-m

It spins quickly although there is little to no corner cutting.
