Customer Comments

  • Is the “hold small children” part true!

  • Has anyone ever been in one of those moods? The kind that make you feel the need to point out that this is a cube, not a square?

  • This might be a silly question, but I am a noob: Will this work well in a Hall Effect set up for a joystick? Or would a bigger/smaller/different shaped one be better? Cheers

  • Hello, I’m from Philippines. Please have a re-stock of this product. We need 10pcs of this for our thesis.

    Thank You!

  • Very strong magnets. Fun to play with.

  • Are these conductive? Can I solder a wire on to one?

    • If you are going for an easy way to connect boards together you might wanna look at the magnet ring listed below.
      [Just came from there and they mentioned that very use in the description.]

      • No… not that. I’m trying to hack some devies with magnetic expansion ports on them, but I just realized I can solder directly on to the ports.

    • They are typically nickel plated, so yes, they are conductive, although I imagine it would be hard to solder to.

Powerful little cubes

The magnet is small, though bigger than I expected for some reason, and really really strong. So it’s exactly as advertised, and just what my project called for.


Absolutely fantastic

Cube magnets are awesome. They are unbelievably strong, and they are relatively cheap. So far I think I’ve bought 10 for 2 refrigerators.
