Video overview

After inspecting the Tornado V3 Premium Flagship SAO Black Core 20MC featured previously, I discovered that it contained an 8MC core instead of the specified 20MC core. I contacted the seller, and the correct 20MC core arrived. This time I disassemble the cube and replace the 8MC core with the 20MC core myself. Along with showing my communication with the seller and unboxing the replacement shipment, I compare the structures of the 8MC and 20MC cores. After the swap, I reassemble, lubricate, and adjust the cube, then check the change in turning feel and perform timed solves. What this video covers: ・How the 8MC core came to be installed ・Contacting the seller and the replacement response ・Unboxing the correct 20MC core ・Structural comparison of the 8MC and 20MC cores ・Disassembling the Tornado V3 and replacing the core ・Reassembly, lubrication, and adjustment ・Turning-feel comparison with the 8MC configuration ・Timed solves and impressions after the 20MC conversion If you watched the previous video, I hope you will also check out this replacement process and its results. I publish videos about new Rubik's Cube products, limited models, internal-structure comparisons, and customizations.
