Review: Really nice cube to use - Decided to relearn the cube after being able to do it 40 years ago. This cube turns easily and smoothly. The magnets really help, in fact this is much better than the cube I had 40 years ago. Ignore the reviews that state it's flimsy and fell apart after their kid used it for 2 days. My guess is the kid got frustrated, pulled it apart to cheat (like back in the day) and broke it. This is very usable. sturdy and solid. As an aside, took me about 30 minutes to solve on 1st attempt. Memory isn't what it was, but there's only a few moves you need to memorise/remember to solve these.
Review: Well made, strong and smooth. - Perfectly smooth and strong, you can turn fast when not completely aligned as desired on a speed cube. I tried pulling the cube apart with a lot of force a bunch of times and it has some stretch in it but does not break. Exactly what is wanted. The magnets give the cube a nice click together.

## Features

- 🧲48 MAGNETS: The Swift Block Magnetic Speed Cube features a patented magnetic chamber design with 48 embedded magnets, ensuring a smooth and stable rotation. The magnetic particles are securely held in place, preventing any shifting. Please note that the magnetic force is not adjustable.
- 👍Adjustable Elasticity: With a patented 5-level elasticity design, you can easily adjust the magic cube's elasticity to your preference without disassembling the cube or using any tools. The 90-degree full fault-tolerant design allows for greater rotation angle deviation, enabling players to manipulate the cube more easily.
- 🌝Lightweight, Durable, and Smooth: The professional speed cube is made of eco-friendly materials and features a wing-shaped steel-plastic axis design that reduces weight, increases stability, and ensures lasting smoothness. The cube is less prone to looseness or detachment, and the stickers are reinforced with a three-leaf snap-on design to prevent falling off, making it more stable and durable.
- 🎁Fun and Educational: The Swift Block 3x3 Magnetic Cube consists of six faces with different colors that can be arranged into approximately 43 quintillion shapes by rotating. However, there is only one solution. Playing with the cube can improve your reaction time, hand dexterity, hand-eye coordination, spatial thinking, problem-solving skills, attention, patience, and perseverance. It also makes a great gift for children, adults, and seniors alike.
