It's about the same size as a Valk 2 M corner; that would make it about 25 millimeters across, or 15625 mm³. This means if you had a hollow box exactly the size of a cubic meter (and a cloning machine), you could fit exactly 64 of the 1x1 in it.

Mm yes, now we're getting somewhere. It has a very buttery feel, and I haven't had any lockups yet. Far better than any GAN cube I've had in that respect.
Based on your description of the cube I conclude that it is not the GoodCube 1x1x1 Cube Dice 1x1 Magic Cube Puzzle, Black but is instead TheCubicle's 1x1 (25cm) cube.
The GoodCube 1x1x1 Cube Dice 1x1 Magic Cube Puzzle, Black is often described as "crinkly", "solid", and "fast". Which does not match your description. What I believe you currently have is the best mass-produced 1x1 on the market (Custom made ones can be better though they are very expensive)
