The DaYan TengYun V3M is the latest 3x3x3 speedcube release from DaYan, it is a bit of a mixture between the original TengYun V1/V2 feel and the GuHong V4M feel, it has lost the very quiet feel seen in the original TengYun V1 but has pretty much completely fixed any popping issue. it has magnets in the feet of the corners and edges and these are the magnets which can actually be adjusted.
