Recently I've been noticing this too. The spring noise is barely noticeable now, but when I first got it... it was unbearable. No really. I only understood the tensioning system after J Perm's vid on the RS3M 2020.
I think the main issue a lot of beginners have is not understanding the mechanics of the puzzle. And I know that is true, based on my experience.
<...>
The RS3M is more like a cube for intermediates, not for absolute beginners. Of course they can choose it if they want to, but if you can't understand the mechanics of the cube, then there's literally no point in buying the RS3M. MoYu uses this system in all of their cubes, and if you love MoYu and want all of their cubes, then yes, go for the RS3M, because it's literally the same as the Worms but cheaper.
TL;DR: The RS3M is a good cube, but not for absolute beginners.
Total noob here with a beginner's perspective. I've been cubing for less than a month on RS3M 2020 with no prior experience with other cubes, except a dirt-cheap abomination from 2003 that I assembled once never to touch it again. My current PB is around 2½ min using roux with only 2 algs, other than that just intuitive, so you get the idea about my speed and dexterity.
I've searched this forum, youtube and user reviews on online stores for a good beginner's cube. The general consensus was 'RS3M 2020 is a great budget cube, on par with others three times its price'. And of course speedcubers on youtube could perform their fast tricks on it quite confidently and impressively.
After disassembling, studying the internals, lubing and setting it up following cyoubx's recommendations, it did enjoy it quite a lot at first. Although I couldn't turn faces in a fast flow, I did try to use fast motions whenever possible. And I thought that overshoots or undershoots (is that a word?) were the problem of my control rather than cube's performance. So I tweaked it around a couple times, but still couldn't get a confident controllable feel.
My general complaints
as a beginner in
year 2021 towards RS3M 2020 are:
1) it is quite heavy, and requires significant force to get a side moving
2) once the side moves, it can easily overshoot, because
3) magnets are weak
4) in order to control it and prevent unwanted moves, I have to grab more pieces
5) the inside and outside plastic is the same material. For tactility (outside) if feels ok, but for friction it feels cheap
6) yes, one can mod the cube to get stronger magnets, but it only adds more weight to the puzzle
7) high expectations play a trick on potential buyer
Now, I understand that speedcubers from 2010 had much worse cubes, and that practice makes perfect. And don't get me wrong, it is light-years ahead of my cube from 2003. Yet still I feel like I am fighting the cube more than enjoying it. Bear in mind that I have only around 40 minutes a day to practice, mostly on the subway, so I don't have the hours to develop dexterity and get used to controlling this specific cube. So I would prefer a cube that helps me instead of standing in my way and to spend that time holding a more quality product, that doesn't feel as cheap.
Regarding the cheap feel: it is a budget cube, what did I expect? But yeah, being a total beginner, I am ready to pay three times more to get a better feeling product, even though I perform terribly at the moment. But I will enjoy learning, at least I hope so. I've ordered a Dayan Tengyun V2, which will hopefully be more enjoyable for me. Once I get it and have some time to compare the two, I expect to come back with more observations on RS3M vs a more expensive alternative as a beginner's cube. As of now (not having held other speedcubes), I consider it to be massively overhyped thus generating false expectations: although it may perform on a semi-pro level (sub15), it doesn't feel like a semi-pro product. It is a budget cube.
My solution is:
-Start of with something simple like a QiYi MS or Warrior or the YLM until you reach Sub 30.
-Get a new cube like the RS3M but preferably within 20 dollars until sub 15.
-Get a new flagship when you get to sub 10, and expand your collection from there.
This is where I beg to differ. I think after reaching sub 30, one can buy a flagship. Instead of buying two cubes (performance cube for sub 30 to sub 15, flagship for sub 15 to sub 10), why not just buy a flagship in the first place, and enjoy the ride from the beginning, plus save the money that would be spent on a performance cube? =)
