The MoYu RS3 M at first seems like it an incredible cube. For its performance at this price it's tough to beat. But the cube comes with some minor flaws and one unfortunate major flaw.

Minor flaws are the scratchy plastic feeling straight out of the box and the terrible spring noises, both easily remedied with lube.

The massive flaw is most likely due to terrible quality control at this price point. The screws on this cube are be extremely prone to stripping and unscrewing themselves, leading to the whole centre face coming off during solves. If MoYu were to somehow fix this issue, this would be must-buy for every cuber, but otherwise, I can't in good conscience give this any more than 2 stars.

My screw loosens itself. I just lubed it and it loosens itself. Idk what to do

Ok, I know there are a TON of review and hype around this cube, and I just wanted to voice my personal opinions on this.

OOTB, this cube is dry, crips, and fast. There was also a significant amount of spring noise on various sides. I applied some core lube (weight 5) and piece lube (DNM-37), and put the dual adjustment to the fourth click. On top of this, I also put in the extra magnets that I purchased into the edges. This cube is now my main.

For reference, I have a self magnetized Yuxin Little Magic, a Little Magic M, a YJ Yulong V2M, and a GAN 356M as 3x3's in my collection. This cube is the only cube that allows me to get sub 16. This cube not only performs excellent with flagship features, but also has premium plastic. Most budget cubes have the problem of having good performance with cheap materials. MoYu has gone above and beyond with their budget cubes (this one in particular), and uses high quality plastic with great color shades. This cube has a very enjoyable/addictive crispy soft feel, and has the best forwards corner cutting I have ever seen (reverse is also pretty good).

With many cubers replacing the expensive flagship cubes with the RS3M 2020 as their main, I believe this raises a bigger question in the cubing market design. Oftentimes, simpler is just better. I don't need a bunch of magnet adjustment (cough cough GAN 11), complex spring adjustment (cough cough Tengyun V2) to get good times. It gives me a peace of mind to set it up and start cubing.

Sorry for the long rant, but in conclusion this cube shines in EVERY SINGLE ASPECT. Except 1. The only fault this cube has (and its a decent one) is its weight. Weighing in at 86 grams stock, and 89 grams with the extra magnet, its a pretty thick boi. Especially when doing long sessions/averages, you can start to feel the weight wear down on your hands, and starts to affect your TPS. It's not a bid deal (especially for beginners), but I can't help but think how good the WRM 2020 performs. Lightweight, same adjustment, and a more compact size, it's the dream cube right? Well yes, but no. Although I'm sure the corner cutting is jsut as good or better than the RS3M 2020, It may feel more "snappy" or "forceful" due to its lightweight (props to cyoubx for this explanation). Maybe cubers have to give and take with heavy cubes and good corner cutting, or light cubes and more forceful corner cutting (GAN cubes have this problem).

If you're a seasoned cuber with many lubes, definitely make sure to check out this cube (also get the magnet kit)
If you're a beginner or someone on a budget, this is hands down the best cube on the market for under $10 (get the magnet kit!) The only reason I would advise you stay away from this, is if 1. You absolutely HATE heavy cubes . 2. You don't want to pay for lubes (this cube NEEDS to be setup).
If you're a beginner, there are essentially 2 types of lubricants. 1 for the core (where the spring and screw make contact), and the other for the pieces. For those on the tightest budget for lubes, I reccoment the "QiYi M-lube" for piece lube, and the "Adheron Heavy" lubricant for the core lube.

Well, if you still stuck around, thanks!
Happy cubing yall

My dad got me this cube because I won a
bet. I wanted this cube because I saw that
Jperm had it, and the shipping was fast.
Overall I got it from speed cube shop
discount code Jperm

It’s pretty bad but I guess it’s worth it for the price

So good! World class!

The cube is great, its just that for some reason the orange and blue screws screw off during solves. The only reason I gave it a 3 star is because of this problem.

This cube made me throw all my Gan cubes in the garbage literally and I will never purchase another until they fix their issues with their cubes and you guys know what I mean. This cube seriously rocks right out of the box. tighten a few turns and it's go to go. I love the plastic on this cube and between the meilong and this cube it's hard to decide which I like more as they are both incredible and budget cubes! I think this is the new standard and I will be reluctant to purchase anything in the 30-40 dollar range ever again. Moyu has gotten me back after not enjoying the wrm series because of the plastic I didn't enjoy too much. Try this one out you will like it :)
