Rubik’s Cube 4×4 QiYi Magnetic (EQY662) — budget magnetic 4×4 for everyday training

QiYi Magnetic 4×4 (EQY662) is a magnetic 4×4 speed cube from QiYi’s affordable product line. The cube is about 62×62×62 mm in size and weighs around 135 g: it feels solid and reliable in the hand, but not like a “brick”.
Magnets are built into the pieces, helping the layers align and making turning more stable and predictable — both on the outer and inner layers.

Who is this cube for

Level:

beginners who have already learned 3×3 and want their first 4×4;
intermediate casual cubers who need an inexpensive “workhorse” 4×4 for practice;
experienced speedcubers can use it as a backup or everyday training cube.

Age:

school-age kids and adults; the size of about 62 mm is comfortable for medium and larger hands.

Main uses:

first 4×4 practice sessions and learning parity cases;
everyday solves “for fun”;
an affordable but already magnetic 4×4 for a collection or as a gift.

Turning feel

QiYi Magnetic 4×4 has a fast, light and slightly scratchy feel:

the outer layers turn fairly quickly and freely, and the cube accelerates well on finger tricks;
the turning feel is not “mushy”, but rather light with a slight “scratching” sound/feedback that many people find pleasantly tactile;
magnets add clarity — layers lock into place more cleanly and wobble less.

For a beginner it feels like a real speedcube, not just a toy; more experienced cubers will appreciate that, even for its price, the cube can be turned at reasonably high speeds.

Magnets and adjustment

Magnetisation:

magnets are built into the pieces around the perimeter, working on both inner and outer layers;
magnetic strength is around medium: layers tend to align by themselves, but the cube doesn’t feel sticky or slowed down.

Tension adjustment:

classic screw-and-spring system under the center caps;
you can tighten or loosen the tension with a small screwdriver, with no special tools or complex systems.

The concept is simple: the cube should be ready to use straight out of the box, and if you want, you can fine-tune it a bit to your preference.

Stability and inner layer behaviour (4×4)

For a 4×4, the behaviour of the inner layers is especially important — and here the EQY662 performs well for a budget model:

the inner layers are slightly tighter and more “dense” than the outer ones, which helps keep the cube’s shape and reduces random lockups;
with reasonably accurate turning, the inner layers move smoothly enough and are not dramatically slower than the outers;
with small misalignments the cube usually does not lock up, but with a very aggressive style you may feel minor catches — which is normal for an inexpensive 4×4.

Overall, the balance is this: outer layers are fast and pleasant, inner layers are stable and predictable. For learning, daily solves and first serious 4×4 training, this is more than enough.

Size, weight, materials

Size: about 62 × 62 × 62 mm — slightly larger than ultra-compact 4×4 models, but more comfortable in the hand for most people.
Weight: about 135 g — the cube feels solid and reliable, but not excessively heavy.
Material: durable ABS plastic designed for frequent use.
Colours and surface: bright stickerless plastic (coloured plastic without stickers) with good contrast between faces; the outer surface is smooth, but not overly slippery.

What’s in the box

A typical QiYi Magnetic 4×4 package includes:

QiYi Magnetic 4×4 (EQY662) cube;
branded box or plastic case;
small leaflet/instruction sheet (usually in English/Chinese).

The cube comes pre-lubed and tensioned, ready to use straight out of the box.

Key advantages

Affordable magnetic 4×4 — a good step up from non-magnetic beginner cubes to more serious hardware.
Fast outer layers and sufficiently stable inner layers — convenient both for learning and for practice.
Medium-strength magnets help maintain shape and control turns.
Comfortable standard size and weight — feels good in the hand.
Simple and easy-to-understand construction without complex adjustment systems — easy to explain to a child or a beginner.

Who it might not be ideal for / nuances

For those looking for a high-end flagship 4×4 with a ball-core, adjustable magnets and an ultra-“buttery” super-smooth feel, this model will seem basic — it’s a solid budget workhorse, not a top-tier flagship.
With a very aggressive turning style and large misalignments, inner-layer catches are possible — serious record-chasing competitors will likely want a more advanced 4×4.
The cube is fairly fast for a total beginner: if the buyer has never used a speedcube at all, it might be more comfortable to start with a slower educational 3×3 and only then move on to a magnetic 4×4.
