MoYu RS3M 2020 3×3 — legendary budget magnetic speedcube

MoYu RS3M 2020 3×3 is one of the most popular budget speedcubes of recent years. It is a classic magnetic version: spring core, edge–corner magnets, modern geometry and a convenient dual center adjustment system. The cube works both as a first serious speedcube and as a reliable “workhorse” for more experienced cubers.

The cube size is about 56 × 56 × 56 mm, the weight is around 80–85 g: it feels a bit more “solid” compared to ultra-light flagships, but still remains fast enough and predictable.

Who is this cube for

Skill level:

• beginners who already know how to solve 3×3 and want to switch to a proper speedcube;
• intermediate cubers who need an inexpensive but reliable magnetic cube for training and local competitions;
• experienced speedcubers — as a spare or “training” work cube.

Age:

• children, teenagers and adults;
• suitable for school kids as a first serious magnetic cube.

Main use cases:

• learning speedsolving on 3×3;
• regular timed practice at home or in a club;
• taking part in beginner and amateur competitions;
• a spare or “outdoor” cube you are not afraid to take anywhere.

Turning feel

• turning is reasonably fast and light for its price range;
• medium-strength magnets help the layers snap cleanly into place, adding control;
• the feel is more soft and stable than extremely “airy” — the cube does not try to fall apart from a tiny flick;
• out of the box it can feel a bit “dry” — after lubing and adjustment it opens up much better.

Overall, RS3M 2020 feels like a solid, predictable cube: it’s not the absolute fastest cube possible, but it offers an excellent balance of speed and control, which is especially convenient for learning and improving your technique.

Magnets and adjustment

Magnets:

• factory-installed edge–corner magnetization (magnets built into the pieces);
• magnetic alignment is clearly noticeable but not excessive — the cube doesn’t “stick” on every click.

Center adjustment system:

• classic screw + plastic element with fixed elasticity levels;
• you can separately adjust tension (with the screw) and overall “stiffness” (with the stepped system);
• the adjustment is quite simple: a bit of practice and you can easily find a comfortable setup for your style.

Stability and corner-cutting

• good forward corner-cutting for a budget flagship;
• reverse corner-cutting is there too, though a bit more modest than on modern top cubes;
• the cube forgives small turning inaccuracies and does not demand perfectly “laboratory” technique;
• with reasonable setup and lube, pops and lockups are rare.

Size, weight, materials

• Size: about 56 × 56 × 56 mm — classic size, comfortable for most hands;
• Weight: around 80–85 g — a bit heavier than ultra-light flagships, but comfortable for long sessions;
• Shell: stickerless (no stickers), bright standard color scheme;
• Surface: usually matte (frosted), small scratches and fingerprints are less visible;
• Construction: closed (capped) pieces, modern internal piece design.

Key advantages

• one of the best price/performance ratios in its class;
• built-in magnets and a convenient center adjustment system;
• balanced speed and stability — great for learning and progressing;
• works both as a first magnetic speedcube and as a training work cube for advanced solvers.

Who it may not suit / nuances

• if you are used to fresh top flagships with MagLev and magnetic cores, RS3M 2020 may feel simpler and more relaxed;
• out of the box it usually needs lube and a little tuning to fully show its potential;
• for those who like ultra-light cubes, the ~80+ g weight may feel a bit heavy.

If you want an inexpensive yet serious magnetic speedcube for practice and improvement, MoYu RS3M 2020 3×3 remains one of the most successful and popular choices in the budget segment.
