I've played with a lot of puzzles over my life. If I could choose one cube, this would be it. This was the first cube that made me want to better my speed. Moving my time from around 2 minutes for years to under a minute. It peaked my interest in learning new methods beyond beginners. It's the customizability that makes it worth it for me. I was always more interested in logic solving many different puzzles instead of speeding up the 3x3. I decided to buy 2 more to have varied setups. And the purple is such a great color.
