MoFang JiaoShi (Cubing Classroom) MF3RS Cube 3x3
[MF3RS]
Honestly, this is probably the best 3x3 for less than five dollars currently. Most 3x3s around its price are missing some major quality, which often is stability. I am happy to say that this cube is stable, fast, and smooth. Its predecessor, the MF3s, felt very blocky and unstable, but this one appears to have a different plastic and a slightly modified design that eliminate those issues. For those reasons, my times on this cube are close to my best times that I get on my main 3x3.
I think MoFang JiaoShi did a great job on this cube, and it certainly is a great buy for anyone looking for an inexpensive 3x3 that is ready to go straight out of the box.
