GAN 251 M Pro — a lightweight, fast magnetic 2×2 built for serious practice and competitive solving, with lots of tuning options.

Manufacturer: GAN. It’s part of the GAN 251 line (51 mm) and combines corner magnets with a magnetic core (corner/core magnet system). Compared to some “Leap” variants, the Pro is typically listed without auto-alignment, focusing on a clean, tunable feel.

Who it’s for

• 2×2 solvers who want a premium feel and fine control over setup (tension/elasticity/magnets).
• Ambitious beginners upgrading from a basic non-magnetic 2×2.
• Competitors who like a fast cube that can be dialed in for control.

Turning / feel

• Quick and “light in the hand” — the low mass can feel very lively.
• Corner magnets plus the magnetic core help tracking and reduce wobble at speed.
• A frosted exterior is commonly listed, aiming for reliable grip without a sticky feel.

Magnets & mechanism

• Magnets: corner + magnetic core system.
• Magnet adjustment: typically 3 strength levels (weak/medium/strong) via switches.
• Tension/elasticity: GAN’s GES system is commonly listed with multiple combinations (including different sets and different travel distances), so you can go tighter or more flexible.

Size, weight & materials

• Size: 51 × 51 × 51 mm.
• Weight: listings most often show ~56–58 g (can vary by spec sheet/batch).
• Material: ABS plastic; typically stickerless (colored plastic).

Main pros

• Wide tuning range (magnets + GES) makes it easy to find your preferred feel.
• Magnetic core adds extra stability during solves.
• 51 mm is a comfortable sweet spot for many 2×2 solvers.
• Fast, smooth, and suited for both training and competition.

Possible nuances

• The light weight can feel “too fast” until you tune it to your style.
• Premium price versus mass-market 2×2s.
• If you want strong auto-alignment, that’s typically associated with other variants rather than the Pro.

How to use

• Solve like a standard 2×2 by turning layers to match colors on all faces.
• For best results: pick magnet strength and GES settings first, then fine-tune to your turning style.

Packaging & what’s included

• Common bundle items: clamshell case, GAN bag, GES spring/nut sets (color-coded), and a small screwdriver for the magnet switches (contents may vary by seller/bundle).
• Some retail specs list a gross packaged weight around 184 g.
