So this cube out of the box was kind of a bit too controllable for my taste. So, what I did is kept turning it until the lube started to break in. After one day of breaking in the puzzle, it reached its best potential. It was very fast but controllable, satisfyingly smooth, soft turning, and incredible performance. This cube reduced my times by a little over half a second! I 100% recommend this but the only problem is the weight and the center caps. The center caps are pain for my nails to take off and the weight in kind of too heavy for my taste. I counted these two things as one star off because the performance takes it all over. This is my new main for sure!

It feels exactly how I want it to feel. I was told Celeritas was a great fit for people wanting to improve their finger tricks, and I have to agree. This cube seems to "reward" the solver for practicing good technique. (the more I reread this, the crazier it sounds... oh well)

If the cube sits for too long, it stiffens up a bit. However, it breaks in again perfectly after just a couple solves, feeling good as new.

The only down-side was the noise. Three of the centers made excessive noise from the springs. So I took out the springs, removed the washers, flipped the washers over, and put it all back.
Boom. No more noise. So, not a big deal really.

After going back and forth between this and my other cubes, I realize none of the others offer enough benefits to justify paying an additional $30-$60 on a cube.
This one has it all.

happy cubing my friends!

Just to get it clear this puzzle is great and at the time of reviewing is my main/backup main. Out of the box the puzzle feels like there are no contact points between the pieces of the puzzle, weirdly it was also felt sandy. This was not my desired feel. After adding it Cubicle Labs Silk, Cubicle Labs DNM-37 and Angstrom Compound 10, the puzzle had a plush, speedy, controllable feel. This made the puzzle great for me. I would also like to mention some other things. The Magnets are a moderate strength that will probably please most cubers. For me the magnets were a bit to strong so I mess up my M’ moves a lot. The Center Cap design is also great because it is just a sleeve. No annoying clips. It doesn’t come out while I shove but it does come out easily when is do want to. And that brings me to my next point. The MoYu dual adjustment mechanism. Before this cube it was only seen on flagship 3x3s. It works very well. Out of the box here it is set at four but I set it at 6 for my personal preference. This brings me to the nit picking things. The celeritas logo is printed on so after you take of the plastic coding it gets all smudgy and you have to wipe it off with a baby wipe or something similar. The size. I have somewhat small so it would be great to see another model that was 54mm. Like I said these are just nit picks. I think this puzzle is great for $20 but I recommend looking at reviews for the MoYu WeiLong WRM2021 because it is $7 more at may be better. I wouldn’t know because I don’t have it yet, you should look at other people’s review on it and listen to yourself and see which one you want more. You should probably take it consideration that this one is fully set up - with lubicle Black on the core and with a tiny bit of more set up it is fantastic. Anyway what I am trying to say is that the Celeritas RS3 M 2020+ gives a lot of bang for your buck. Thanks for reading my honest review of the Celeritas RS3 M 2020+

The RS3 M 2020+ is an outstanding cube on it's own. The extra magnets really give it a solid feel. When you add the Celeritas lube system to it, it's pure magic! I will say, if you like a gummy cube, this isn't for you. This is a thinner, lighter lube that gives a glide/floating on air sensation. I find it very controllable. If you want it a tad faster a drop of the reagent B will speed it up, but be ready. I can't say enough good things about it. Great cube with my favorite of the premium setups. It's my new main.

I bought a stock version of the RS3 2020 and loved it. The matte plastic wears off and becomes grippy, so dont even consider this as a con. The stock version was great, but the light magnets was an issue issue for me, even after adding traxxas 30k + gravitas. But still, useable.

Releasing the 2020+ was amazing. The added magnets barely add any additional weight, but offer way more stability.

The celeritas combo makes this cube INSANELY quiet. Extremely smooth. The setting is stock at 4 spring compression, which actually works. Cube is still fast, controllable, and a joy to solve.

Dropping $20 bucks for a professionally set up cube in this economy is worth it. Instead of dropping $35-60 on other cubes, you can still get your average on this cube :) [I'm sub-15 lol].

What a great cube! I was very surprised that this cube can turn this well for this cheap! Very good investment, and I prefer mine over some GAN cubes(personally). Overall a great buy, and definitely would recommend this to anyone looking for a good cube around $20.

This is by far the best 3x3 I’ve ever had, and i definitely love the speed it comes with, maybe needs a bit of setup if you prefer tighter or looser but amazing cube

This is my first Celeritas cube and I like it a lot. I do not think it is a contender with any flagships but considering this is only $20, it is very good for the price. Right out of the box, it was very slow. A few solves later, it was a bit faster. 20 solves later it feels the same. The cube itself is very blocky and sounds way different from many cubes I have at the moment. There was also a slight spring noise but is only noticable if you put your ear right next to the cube and turn very slow. After a while though it went away. The main reason I am giving this cube a 5 star is because of the price. If you want a higher quality cube, then you should get the GTS2 or 3. But great cube (for its price).

This cube came perfect and has replaced the GTS3 M as my main!

... and I couldn’t be happier. I have a lot to learn but it’s nice having the peace of mind that my cube will never hold me back!
