(I got this cube from the old thecubicle.us site so this may not show as a verified purchase. But I assure you I got it from there. I just only got around to reviewing it now.)
So I got this cube because of all the hype surrounding it (Two actually. One I magnetized with TheCubicle's Strong Magnet kit to compare) and it did not disappoint! It's incredibly flexible in that it can easily cut 45 degrees or more depending on your tensions/preference. It also reverse cuts about 1/3 of a piece, which is incredible for preventing lock ups. Said lock ups are basically non existent really as there's only a very small area in the middle of a turn where it won't turn in either direction. Speaking of turning, it's so smooth and consistent feeling on smaller corner cuts it's nutters! It's like there is air between the pieces as they glide against each other effortlessly. I also got this cube in stickerless which is glossy and thus has a nice grip. The stickerless colors are easy to tell apart from each other as well even in low lighting due to their nice contrasts and color shades. The only issue I've had is spring noise which is prominent on certain faces even after adding a thick lube to the hardware. But that doesn't affect it's actual performance and is more of a pet peeve.

Over the last year or so I’ve owned 5 magnetic versions of these (2 black, 3 Stickerless). If you’ve got the time and money to magnetize this, then do it. I recieved a custom Boron one from a friend at a recent comp, and so far it’s the smoothest thing ever. Long story short......just get this and some magnets and you’ll never need to buy another 3x3 ever again !!

I got this in July. OOTB it was really fast, unstable and floppy. The next day I magnetized it with strong (N50 5×1) magnets and lubed it with Lubicle 1 on the pieces and Traxxas 50k on the core, tracks and pieces, and I left the tensions as they were. The cube became the exact opposite of its OOTB feeling: very stable, a bit slow, but, most importantly, very very very soft and quiet.
It's now my OH main and two handed backup main because it's simply so controllable.
In the end, I reccomend this cube to anyone looking for a budget, yet fenomenal cube that has a soft and blocky feeling. For the price of only $8+$8 for the magnets, you really can't go wrong.

Out of the box the cube is smooth. The corner cutting is incredible (reverse is about 45 and normal is passed that). I would definitely recommend this cube.

I got this cube in stickerless and I think the shades are perfect.
When I unboxed it, the cube was a little too tight, and the corner-cutting was around 45 degrees with some effort.
To set it up, I put Traxxas 50k in the core and pieces, worked it in, and then added 2-3 drops of DNM-37 in it afterwards.
Now, it is super smooth, controllable, and can corner-cut much past 45 degrees with ease. It is my main, and currently I am sub-18, so that's saying a lot, especially because of its cheap price of $7.99.

TL;DR: The MF3RS2 is a great budget cube that is smooth, controllable, and has great corner-cutting. I definitely agree with the color scheme and recommend it to any cuber ranging from beginner to expert.

I had gotten a Stickerless one of these and magnetized it. Have had this for a few months now and have used it in a few comps, achieving a 14.62 PB average. Recently I bought 2 black cubes, a lite and strong magnet kit, and the angstrom lube bundle. After hours of magnetizing and setting it up similar to and angstrom cube, it’s gotten even better than my stickerless one. I plan on using the one with strong magnets for 2 handed, and the lite magnet one for OH.

It was a little dry and tight out of the box. After setting up and a little bit of breaking in, this cube felt better, smother ,and more controllable than my Gts2.

This cube is one of those cubes rarely found. THis is a great budget cube and is even better than most expensive cubes to me. Out of the box it was really smooth but had a bit resistance. After breaking in i knew this could possiby be my main. GREAT JOB MOFANG!!!

My friend got this cube and i tried touse it and it was so smooth. Best price for $4.99

Out of the box this cube was ok. It was pretty stable and was a bit slow. But i magnetized it with 5x1 n48 magnets and i lubed it with DNM-37 and Now it is a really great cube. But i have 3 problems with it. The first one is that when i accidentally make an inacurate turn, when it is forced to corner cut, the design of this cube makes it lock up sometimes

The second problem is that when it corner cuts, the tensions get looser. For example, the screw that connects the middle with the center starts to come off when i corner cut and as a result it has popped a few times with the middle piece also coming off. But maybe mine came flawed and yours wont do that. The last problem is the spring noise. Its not too bad and ime pretty sure it can be fixed. Overall this is a really great cube that is Totally worth your 8 dollars.
