MoYu RS4M 4×4 — affordable magnetic 4×4 for entering the world of big cubes

MoYu RS4M 4×4 is a budget magnetic 4×4 from the well-known RS line. It’s designed for cubers who want to move from basic non-magnetic puzzles to a more modern and stable 4×4, without paying flagship prices.

With built-in magnets, a solid internal design and comfortable turning resistance, RS4M works very well both for learning the event and for your first timed solves — at home, at school or in a local cubing club.

Who is this cube for

Skill level:

• beginners who already solve 3×3 confidently and are starting 4×4;
• casual and intermediate cubers who want an inexpensive but magnetic 4×4;
• school clubs and classes where price, reliability and easy setup matter.

Age:

• kids around 9–10 years old with basic 3×3 experience;
• teens and adults practising at home and with friends;
• a solid choice as a first magnetic 4×4 in a collection.

Main use cases:

• learning 4×4 and stepping up from 3×3 to big cubes;
• regular home practice and casual mini comps;
• use in schools, studios and learning centres;
• a daily trainer for drilling core 4×4 algorithms.

Turning feel

• reasonably light and fast turning for a budget 4×4;
• magnets provide a clean click and help layers align properly;
• outer layers feel smoother and quicker, inner layers slightly firmer for stability;
• moderate sound level without excessive rattling — comfortable in rooms and classrooms;
• forgives many small beginner mistakes and doesn’t require perfect technique.

Overall, MoYu RS4M 4×4 feels like a simple, intuitive and beginner-friendly practice cube that makes learning 4×4 much easier.

Magnets, stability and corner-cutting

Magnetic system:

• built-in layer magnets help the cube lock in after each turn;
• magnetic strength is light-to-medium — layers are guided but turning still feels free;
• reduces random underturns and shaky, misaligned layers.

Stability and corner-cutting:

• stable enough for learning and casual speedcubing;
• corner-cutting on par with a good budget magnetic 4×4;
• with a reasonable setup, the cube rarely locks up and is not prone to pops under normal turning.

Size, weight and materials

• Size: close to standard 4×4 size (around 60 mm), comfortable for both kids and adults;
• Weight: light-to-medium — doesn’t tire your hand even in longer sessions;
• Shell: bright plastic with clear, easy-to-read colours;
• Surface: usually slightly matte, less slippery and friendly for smaller hands.

Key advantages of MoYu RS4M 4×4

• one of the most popular budget magnetic 4×4s from MoYu;
• great balance of price, speed and stability;
• suitable for both learning and first timed attempts;
• easy to set up with predictable behaviour as you get faster;
• an excellent first magnetic 4×4 for kids and beginner cubers.

Who it may not suit / nuances

• very advanced speedcubers may find it below high-end flagships in max speed and corner-cutting;
• if you’re used to ultra-light turning and complex core systems, RS4M will feel simpler and more classic;
• if your goal is top-tier competition results, you will probably want to upgrade to a flagship later.

MoYu RS4M 4×4 is a great starter magnetic 4×4 for anyone who wants an affordable and comfortable entry into big cubes and 4×4 speedcubing.
