The YuXin Hollow is a very weird cube, it weighs just 49 Grams which makes it significantly lighter than any other normal sized 3x3x3 on the market. It is an interesting product that also reminds me of Chris Tran's last speedcubing project where he hollowed out an RS3M 2020 (a cube which Patrick Ponce probably used in his OH WR average), unfortunately this does not perform anywhere near that level, I might magnetize it at some point just in case it is any better but that seems unlikely.
