MoYu Super RS3M V2 Ball Core (UV) — modern 3×3 with a ball core and grippy UV finish

MoYu Super RS3M V2 Ball Core (UV) is an advanced version of the popular Super RS3M line, featuring a spherical ball core, core magnets and a glossy UV-coated shell. It combines high speed, stability and a tacky grip while still being more affordable than many full flagships.

In practice it’s a “semi-flagship”: in feel and performance it comes close to MoYu’s top cubes, but at a price that makes it realistic as a main trainer and competition cube for a wide range of cubers.

Who is this cube for

Skill level:

• confident beginners and intermediate cubers who have outgrown a basic RS3M;
• advanced cubers wanting a fast, stable main without paying full flagship prices;
• competition solvers who want a reliable ball-core cube with solid control.

Age:

• teens and adults who train speedcubing seriously;
• kids around 9–10 years old who already solve 3×3 confidently and treat cubes with care;
• as a first cube, it suits motivated beginners who want “real performance gear” from the start.

Main use cases:

• daily practice and algorithm drilling (CFOP, Roux, etc.);
• competition preparation and use as a main training/competition cube;
• chasing personal bests and stable averages;
• an upgrade from standard RS3M and other entry-level magnetic cubes.

Turning feel

• turning is fast and light, and the cube ramps up to high TPS easily;
• “on rails” feel — the ball core gives a more solid, predictable layer movement;
• magnetic click is medium in strength, helping you hit 90° cleanly and reduce overshoots;
• sound is soft and fairly quiet, comfortable for home and practice halls;
• suits both aggressive and more careful, technical turning styles.

Overall, Super RS3M V2 Ball Core (UV) feels like a fast yet controlled cube: it forgives small mistakes and doesn’t fall apart in your hands even at high speed.

Ball core, magnets and adjustment system

Ball core and core magnets:

• corner pieces are magnetically “linked” to the core, improving layer centering after each move;
• the cube wobbles less and holds its shape better at very high TPS;
• the feel is more compact and “monolithic” than with a classic non-magnetic core.

Edge and corner magnets:

• magnets create a consistent magnetic track throughout the cube;
• magnetic strength is tuned not to choke speed, but to add a healthy amount of control;
• most cubers will like it straight out of the box; further tuning is done with lube and tension.

Adjustment:

• modern system for regulating tension and elasticity;
• you can make the cube looser and faster, or tighter and more locked-in;
• once adjusted, it holds settings well without constant screw retightening.

UV finish, stability and corner-cutting

• glossy UV finish provides a tacky grip — fingers slip less at high TPS;
• the UV layer better resists nail marks and small scratches;
• forward corner-cutting is at modern flagship level, handling typical misalignments with ease;
• reverse corner-cutting smooths out small mistakes and reduces lockups;
• the design significantly reduces the risk of pops and accidental corner twists.

Size, weight, and usage profile

• Size: compact 3×3 (around 55–56 mm), comfortable for most hands and for OH;
• Weight: light to medium — comfortable for long practice sessions;
• well suited as a main cube for training, competition and everyday speedsolving.

Key advantages of MoYu Super RS3M V2 Ball Core (UV)

• ball core and core magnets for high stability and “on rails” feeling;
• fast, predictable turning that works with many solving styles;
• grippy, durable UV coating on the shell;
• near-flagship performance at a more accessible price point;
• an excellent upgrade after standard RS3M and other budget cubes.

Who it may not suit / nuances

• complete beginners who are fine with a very simple starter 3×3;
• cubers who dislike glossy UV grip and prefer a matte surface;
• if you want absolutely all the newest tech (MagLev + ball core + AI, etc.), MoYu also offers even higher-end flagship models.

MoYu Super RS3M V2 Ball Core (UV) is a great choice if you want a fast, stable and grippy cube with a ball core and UV finish, without paying full flagship prices.
