The Spark 7x7 V2 M is an X-Man Design 7x7 with magnets and a ball-core setup (corner-to-core magnets) that adds auto-alignment and noticeably more stability. It’s around 64–64.5 mm and about 160–163 g, so it feels smaller and lighter than many 7x7s.

Who it’s for

• For cubers who prefer compact big-cubes and less hand fatigue.
• For anyone chasing stability and alignment help from a ball-core system.
• If you want very strong “snappy” magnets, note that magnet strength is often described as moderate.

Turning / control feel

• Ball-core (corner-to-core) gives a calmer, more centered feel during fast transitions.
• Compact size makes grip and outer-layer control easier.
• Auto-alignment helps layers return to line after quick turns.

Magnets & mechanism

• Magnets: yes, including corner-to-core magnets via the ball-core.
• Magnet strength is commonly listed as moderate.

Size, weight & materials

• Edge length: about 64–64.5 mm.
• Cube weight: about 160–163 g.
• Color: stickerless.

Main pros

• Ball-core stability and auto-alignment on a 7x7.
• Very compact and lightweight for the category.
• Easier control over long practice sessions.
• A good pick if you like a more “modern” big-cube feel.

Possible drawbacks

• Moderate magnets may feel too subtle for fans of strong magnetic snaps.
• Smaller size can take a bit of adjustment if you’re used to classic 7x7 dimensions.

How to use

• Solve with standard 7x7 methods; the ball-core mainly helps stability during fast sequences.
• Do basic tension setup and add a small amount of lube if needed.

Box & contents

• Comes in a factory box; included extras can vary by batch.
• Gross packaged weight is listed around 265 g.
