I started on a Rubik's brand recently then was gifted a QYToys non-magnetic 3x3, and there was no way I could ever go back to a Rubik's cube. Now, I have this SCS magnetic 3x3 and there is no way I could ever go back to the QYToys - it's that much of an improvement.
I'm still a complete beginner, but this cube improved my solve time by 20 seconds on average the first day I got it out the package, and has been a joy to learn beginner CFOP on. It feels good in the hand, magnets are just right, it's adjustable and the price is unbelievable. Love it!
