Not much to say. Nice, sturdy, smooth, quality cube.

Dear Reader: Don’t make my mistake. I bought original brand Rubik’s Master, the 4x4 cube. As much as it pains me to speak against the original ingenious puzzle toy…this 4x4 cube is FAR superior to play with. Buy this one, do not buy the original.

Had it for a few weeks now. It's much better than my rubiks brand cube! Corner cuts really great, turns fast, and the spring tensions are adjustable if you pop the center caps off. Im relatively new to speedcubing, so im not that fast, but I can get times of 40-70 second solves using the my main method, beginner cfop. I certainly wouldn't get that on a rubiks brand cube! It comes unlubed out of the box, and while its okay without lube, it will boost the performance by a lot. As for piece pops, its not that hard to re assemble if you have a brain. if a corner piece pops, take out a corner adjacent to it, then take out the edge piece, put the 2 corners back, then the edge piece. If you were to put the corner which popped out back in without taking anything else out, it would require alot of strength with an almost fully assembled cube. If you're re assembling it from scratch, i'd reccomend getting the edge pieces of one color in first (It will pop a few times, you'll eventually figure out how to not have it pop) then get the first layer corners in, then build on to the second layer, following the one piece pop tutorial for the last piece in the top layer.I used this exact procedure to clean out my cube when it debris with pebbles and dirt when I took it with me to watch fire works, and sat on a dirt/rock path with it. Overall, its insanely good!

Nice and smooth and it corner cuts great and it feel fast but magnet make it feel sturdy

So I made the silly mistake of using bad lube on my other 4x4. I bought this one as a replacement. I love it, the magnets are amazing and just lines up the sides perfectly all of it moves very smoothly. The quality is also great for its price, it could be better but it really is amazing. Everything works great out of the box too and can be slightly adjusted. I highly recommend

So this is the third cube I bought in as many weeks. Started with a Rubik’s cube from Target, then a speed cube, a now the magnetized RS3M.I have really enjoyed using this cube, with drastically easier maneuverability over Rubik’s brand it made learning how to solve not such a hassle. Prior to purchasing, I could not solve, and now I can. Just saying because I can’t truly attest to the speed factor of the cube because, we’ll that’s not me… but YouTube seems to have many great reviews.Downside is it is cheaper on many of the cubing websites… but you’ll pay shipping. So you can pay for shipping or you can pay for Amazon convenience. I myself actually ordered another one because I like this one enough from one of those cube sites. In addition to a few other things. But I liked this one enough to buy an additional one

I love this cube. I have an MGC 4x4 and this Moyu RS4M, and honestly the RS4M is smooth, fast, durable, and it has an amazing feel. It might be a tad bit heavy but you won’t be able to notice after you start cubing. It is a great budget cube and I really recommend this cube!

I have pictured four decent cubes ranging in price from $4 to $25. This cube wasn't the most expensive, it's the median-priced cube, but for my use, it's every hit as good as the most costly cube. This is the one I'd get if you're just starting, or if you want to try something new.It turns smoothly, and still kind of clicks into place when it's square so that it's not too mushy.
