MoYu RS3 M 2020 3×3 — Black: budget magnetic speedcube on black plastic with stable, controllable turning

MoYu RS3 M 2020 3×3 Black is one of the most popular budget magnetic 3×3 speedcubes. It comes with factory-installed magnets, a classic spring-based core and a dual adjustment center system, making it easy to tune for different turning styles. The turning is smooth and fairly fast, with a good sense of control.

The Black version uses a black plastic base with traditional color stickers. It is a great choice for cubers who want a serious magnetic cube for practice and competitions without paying flagship prices. It works very well as a first “proper” speedcube after a basic non-magnetic cube.

Who is this cube for

Skill level:

• beginners who already know how to solve 3×3 and want their first magnetic cube;
• intermediate cubers who practice regularly and need a stable budget main;
• advanced cubers looking for a reliable training cube they are not afraid to use heavily.

Age:

• kids around 8–9 years old and up, teenagers, and adults;
• can be a first speedcube for a child, preferably with some help from an adult for basic setup;
• most interesting for users who already know a beginner or CFOP-style method.

Main use cases:

• daily practice and learning new algorithms;
• affordable main cube for local competitions;
• upgrade from a toy-like non-magnetic 3×3 to a serious magnetic speedcube;
• a gift for a child or teenager who has recently become interested in speedcubing.

Turning feel

• turning is smooth with a slight “sandy” or “bumpy” feel out of the box that improves with break-in and lube;
• speed is medium-to-fast: the cube does not fly out of your hands, but allows confident aggressive turning;
• medium-strength magnets give clear clicks and help align layers without feeling overly stiff or locked;
• sound level is moderate — not ultra-quiet, but not uncomfortably loud either;
• forgives small inaccuracies well, though at very loose settings small catches can sometimes occur.

Overall, MoYu RS3 M 2020 leans towards a controlled, precise style without feeling sluggish — it is obedient and predictable, offering a good balance of speed and control for practice and for early competition use.

Magnets and adjustment system

Magnets / Adjustable magnets:

• factory-installed edge–corner magnets;
• magnet strength is fixed at a medium level (no separate magnet adjustment);
• magnets add stability, help align layers, and reduce overshooting during fast turns.

Core and centers / Springs / MagLev:

• classic spring-based system (no MagLev and no ball core);
• dual adjustment system in the centers with separate tension and stepped compression settings;
• easy to find a balance between a looser, faster feel and a tighter, more stable setup;
• adjustment is straightforward and friendly even for users tuning a speedcube for the first time.

Stability and corner-cutting

• forward corner-cutting is on par with modern budget magnetic cubes and sufficient for most styles;
• reverse corner-cutting covers small misalignments well, though not as extreme as high-end flagships;
• stability is good — the cube generally keeps its shape even under faster turning;
• basic anti-pop features mean true pops are rare at reasonable tension settings.

Size, weight, materials

• Size: about 56 × 56 × 56 mm — standard 3×3 size;
• Weight: around 80–85 g, giving a solid but not heavy feel in the hand;
• Shell: black plastic base with traditional color stickers;
• Surface: glossy stickers with good color contrast;
• Internals: light-colored plastic with molded tracks to reduce friction and hold lube.

Key advantages of MoYu RS3 M 2020 3×3 Black

• very affordable price for a fully magnetic 3×3 speedcube;
• good balance of speed and control, suitable for learning and improvement;
• simple, beginner-friendly center adjustment system;
• stable behavior that forgives mistakes and rarely pops at normal tension;
• classic black-base look with stickers for fans of traditional cube aesthetics.

Who it may not suit / nuances

• may feel slightly sandy or rough out of the box and benefits from break-in and lubrication;
• not as refined, quiet, or feature-rich as modern flagship cubes with advanced cores;
• stickers can wear out or chip over time compared to stickerless plastic versions.

MoYu RS3 M 2020 3×3 Black is an excellent choice for beginner and intermediate speedcubers who want an affordable magnetic 3×3 on black plastic with stable turning, easy adjustment, and a solid balance of speed and control for both practice and early competitions.
