Rubik’s Cube 7×7 QiYi QiXing S2 (EQY818) — budget 7×7 for your first “big” cubes

QiYi QiXing S2 7×7 is a budget non-magnetic 7×7 cube from QiYi, aimed at beginners in big cubes and casual cubers. It’s a speed cube, but first and foremost a stable one, with a bright stickerless body and smooth turning.
The cube measures about 67 × 67 × 67 mm and weighs around 180 g — it feels solid and reliable in the hand, but without that “brick” feeling.

Who is this cube for

Level:

• beginners who already comfortably solve 3×3 and 4×4, maybe 5×5, and want their first 7×7;
• intermediate casual cubers who need an inexpensive workhorse 7×7 “for home and practice”;
• experienced speedcubers — as a training/backup 7×7 you’re not afraid to turn endlessly.

Age:

• school-age kids and adults; the 67 mm size is comfortable for medium and larger hands.

Main uses:

• first steps into the world of big cubes (7×7 and above);
• training parity cases and long algorithms;
• relaxed everyday solves “for fun”;
• an affordable yet quite serious 7×7 for a collection or as a gift.

Turning feel

QiYi QiXing S2 7×7 provides a smooth, fairly light turning feel with an emphasis on predictability:

• outer layers turn smoothly and evenly, without heavy “grittiness”;
• the speed is more on the medium side: the cube can be fast, but it doesn’t try to “fly out of your hands” — which helps control long algorithms;
• in feel it’s not an aggressive racing flagship, but a stable, beginner-friendly 7×7.

For those just moving into big cubes, this is a plus: it’s comfortable to turn, the cube doesn’t scare you with excessive speed and behaves predictably.

Magnets and adjustment

Magnetisation:

• QiXing S2 is a non-magnetic 7×7, there is no magnetic layer alignment inside;
• layer positioning is provided by the mechanism geometry and proper tensioning.

Tension adjustment:

• classic screw-and-spring system under the center caps;
• you can tighten or loosen the tension with a small screwdriver;
• no complex dual-adjust systems, numerical nuts, etc. — maintenance is simple and understandable even for a beginner.

The idea of the model is maximum simplicity: take it out of the box, tweak it a bit if needed — and you’re ready to practice.

Stability and inner layer behaviour (7×7)

For a 7×7 it is especially important how the inner layers behave — and there are many of them here:

• the inner layers are set slightly tighter than the outer ones — this helps the cube keep its shape better and reduces layers “sliding apart” during fast turns;
• 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 and strong misalignments you can get catches — this is normal for most non-magnetic budget 7×7 cubes.

Overall, the balance is:
outer layers turn comfortably enough for finger tricks, inner layers give a feeling of stability and control. For learning and regular training this is more than sufficient.

Size, weight, materials

• Size: about 67 × 67 × 67 mm — more compact than older bulky 7×7 cubes, comfortable for average and fast grips.
• Weight: around 180 g — the cube feels serious and reliable, but your hand doesn’t get tired too quickly.
• Material: durable ABS plastic designed for frequent use.
• Colours and surface: bright stickerless plastic (coloured plastic without stickers) with good contrast between faces; the surface is smooth but not overly slippery — it’s easy to distinguish colours and keep a secure grip.

What’s in the box

A typical QiYi QiXing S2 7×7 package includes:

• QiYi QiXing S2 7×7 (EQY818) cube;
• branded cardboard or plastic box;
• small leaflet/instruction sheet (usually in English/Chinese).

The cube comes preassembled, lightly lubed and ready to use straight out of the box. If you wish, you can later add some lube and slightly adjust the tension to your taste.

Key advantages

• Affordable 7×7 — a great first big cube after 5×5.
• Smooth, predictable turning — comfortable for learning and training without fighting the cube.
• Inner layers tuned for stability — fewer random lockups and misalignments with careful turning.
• Comfortable size and weight — you can turn it for quite a while without heavy fatigue.
• Simple, easy-to-understand construction without complex adjustment systems — easy to recommend to kids and beginners in big cubes.

Who it might not be ideal for / nuances

• For those looking for a magnetic 7×7 with auto-alignment and a more aggressive, “sporty” character, QiXing S2 will feel too simple — it’s a non-magnetic budget option.
• Advanced competitors chasing record times in 7×7 will eventually want a faster, more advanced flagship (with magnets and a more “slippery” feel).
• For people not used to big cubes at all, the size and number of layers can feel unusual at first — sometimes it makes sense to get comfortable with 4×4 and 5×5 before moving up to 7×7.
