The YS3M now comes in 5 different options! This 20 magnet ball core version follows on from some of MoYu's other cubes with the 20 magnet ball core version such as the super weilong and weilong v9. The YS3M has a more stable feel and is used by some good blindsolvers, I have been able to get some pretty good times on this 20 magnet version, however I am very skeptical on the benefit it offers over a regular 8 magnet ball core.
