Since Rubik's is considered the best for it their hardware is automatically awful. For clock it is hard to see how it could be improve drastically. Magics were worse for hardware the variation you had was basically none and the strings broke all the time. Restringing was a pain.1. I haven't seen I clock IRL ever but I already know how to solve it.
2. It's not a twisty puzzle.
3. It's so trivial that people get 5 second averages even though the hardware is *%$&&^ that the Rubik's brand is considered the best.
4. U need to be right next to the puzzle to even tell if it's solved
5. It's people spinning wheels that always look the same to alter little clocks that u either can't see because ur standing in the wrong place or the solvers thumbs are in the way or both.
