I totally agree to this. I think it is a bit confusing as for a beginner to understand (Dual spring tensioning and all that) and would really like Moyu to release a "beginner cube". It's good, but not as a first cube.The RS3M is more like a cube for intermediates, not for absolute beginners. Of course they can choose it if they want to, but if you can't understand the mechanics of the cube, then there's literally no point in buying the RS3M. MoYu uses this system in all of their cubes, and if you love MoYu and want all of their cubes, then yes, go for the RS3M, because it's literally the same as the Worms but cheaper.
