Video overview This video introduces all five 3×3 models from emerging speedcube manufacturer ES Cube.
In the second half, I unbox and disassemble the EStar Air 20M Transparent and compare it with the standard Air 20M.
Inspecting the internal structure revealed an unexpected feature:
the Transparent version also has magnets in the edge feet.
Despite sharing the “Air 20M” name, it may be more than just the same cube with transparent plastic. I take it apart and examine how its internal structure differs from the standard version.
The following five models are featured in the video:
EStar Air 8M — $14.99
EStar Air 20M — $22.99
EStar Air 20M Transparent — $22.99
ES3 8M — $14.99
ES3 20M UV — $35.99
I also explain the ES Cube brand, its basic design and adjustment system, the magnet layouts of the 8M and 20M, and the differences among the models.
The main highlight is the EStar Air 20M Transparent's edge-foot magnets.
I test the cube to see how this difference from the standard version affects its turning feel.
