The O2 Cube (Spinner version) is QiYi’s hybrid 3×3: you can solve it, and the centers can spin like a spinner. The center caps are swappable (mix & match). It’s non-magnetic, about 53 mm in size and about 94 g in weight (without packaging).

Who it’s for

• Anyone who wants a single pocket toy for solving + fidgeting.
• Beginners and casual cubers who value fun over competition feel.
• If you want a pure speed-training cube, a modern magnetic 3×3 is a better pick.

Turning / control feel

• Spinning centers add a “toy” vibe and can be distracting for timed solves.
• It’s typically enjoyed more as a fidget 3×3 than as a competition model.

Magnets & mechanism

• No magnets.
• Swappable center caps let you customize the look.
• Grip divots on the shell help it sit in the fingers.

Size, weight, materials

• Size: about 53 × 53 × 53 mm.
• Weight: about 94 g (without packaging).

Main pros

• 2-in-1: 3×3 + spinner fidget.
• Customizable center caps.
• Grip-friendly shell details.

Potential cons

• Non-magnetic: less self-alignment than modern speedcubes.
• Spinner centers aren’t ideal if you want a classic 3×3 feel.

How to use

• Solve it like a standard 3×3.
• For fidgeting: spin the center; swap caps if you want a new look.
