Our Promise to You
All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.
Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.
The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

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.
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
