I was looking for something different from the standard Rubik's cube - not another generic 3x3, but something that would actually challenge experienced solvers in a new way. After researching void cubes (cubes without center pieces), I found this QiYi model for $3.34. The concept intrigued me: all the complexity of a 3x3, but with hollow centers that change both the visual and solving experience.

What You Actually Get

This is a standard-sized 3x3 mechanism with magnetic positioning and UV coating, but without the traditional center pieces. The result is six square holes that let you see straight through the cube. The magnets are embedded in the pieces and provide subtle alignment assistance during turns. The UV coating gives it a glossy, durable finish that feels more premium than the price suggests.

The turning mechanism is surprisingly smooth. Each face rotates with consistent tension, and the magnets provide just enough snap to help pieces align without being overpowering. It comes with basic solving instructions, though if you can solve a regular 3x3, you can solve this.

What's Good and What's Not

What impressed me: The build quality punches well above its price point. The magnets actually work - you can feel pieces clicking into place during fast turning sequences. The hollow design creates interesting visual patterns during solves that regular cubes can't match. For speedcubers, being able to see internal layers can help with lookahead.

The limitation: If you accidentally pop pieces (and you might during aggressive turning), reassembly is trickier than with a standard cube since you don't have center references. Also, the magnetic strength, while good for the price, isn't as refined as what you'd get in a $15+ speed cube.

What $3 Usually Gets You

At this price point, you typically find poorly-made knockoffs with scratchy turning, cheap plastic that starts chipping within weeks, and zero special features. Most magnetic cubes from recognized brands start around $10-12. Budget cubes under $5 usually sacrifice build quality for price.

QiYi Void Cube Review: Is This $3 Magnetic Puzzle Worth It?

This QiYi delivers magnetic functionality and smooth turning that you'd normally expect from cubes costing 2-3 times more. The difference is immediately noticeable if you've handled cheap alternatives.

Buy It If / Skip It If

Buy it if: You can already solve a regular 3x3 and want to try something different. You're building a cube collection on a budget. You do speedcubing and want an interesting backup cube that won't break the bank.

Skip it if: You've never solved any cube before (start with a regular 3x3). You prefer non-magnetic cubes. You need something that can withstand very rough handling by young kids.

My honest take: 7/10. It's a solid puzzle that delivers more than it promises, with the main limitation being that it's still a $3 cube at heart.

Price: $3.34 (was $6.98)
