A lot to say about this cube.

One of the smoothest, if not the smoothest cube that I own, especially after set up. The 55mm size and added corner/core magnets seemed ideal for one handed, but as soon as I felt how smooth the M slices were I knew this cube was something special. My hands are on the larger side, so I initially thought the smaller size wouldn't interest me enough to switch from my Gan 11 M Pro, but this WRM makes my Gan cube feel a little large, and I actually prefer the size of the WRM. That wasn't the only surprise over the few weeks I've had to formulate my thoughts on this cube though. I thought I preferred strong magnets, but the strongest magnetic setting was actually so strong it started to tire my fingers out after long sessions. And I found the default "3" setting to have a decent magnetic strength for me while still retaining that smooth WRM feeling. There's actually a lot of different ways to set this cube up, all with slightly unique feelings, and I haven't found a setting I didn't enjoy.

However, the corner/core magnets weren't as strong as I thought they'd be. So it didn't feel as stable as my Gan 11 M Pro (set to the strongest magnetic setting as I prefer it.) The corner/core magnets are actually spaced quite a bit from each other, and I don't have a standard WRM 2021 to compare it to, to see how big of a difference this is actually making to the cube, though I'm sure it at least helps a bit. I figure this was done to retain more of a standard smooth WRM 2021 feeling, but I ordered this cube expecting something more comparable to the Gan 11 M pro corner/core system that this cube is inspired by. This didn't end up being an issue for me though, as I got a bit crafty and added extra "MOYU RS3 M 2020+ MAGNET KIT" magnets to the corner pieces of the corner/core magnets. This increased the weight and might take some getting used to, but I actually don't really mind it as now the cube has strong enough magnets to complete the turns and snap themselves into place similarly to the Gan 11 M Pro. It's now incredibly stable and fast, and considering I have tensions really "loose", I wouldn't be able to tell. The M slices might feel a bit less smooth than before adding extra magnets to the corner pieces, but they're still fast and effortless. Maybe just a bit "crunchy" now. In general, this cube feels effortless when turning casually, but still handles aggressive turning equally as well. Feels similar to my "Tymon's WRM (2019)", except less clacky and fewer lock ups due to being spoiled with corner/core magnets adding extra stability. This is my favorite WRM, and I'm choosing to main this over my Gan 11 since I prefer the size and perform equally as well on this cube and even got a new PB single. Though I had the soft texture'd Gan 11, which is peeling and discoloring on the white side anyways. :/

The only downsides I can think of was the matte finish that this cube arrives with, though I knew that would wear off with time, and it did with in the first week of use. And the magnetic strength takes forever to change, which is kind of annoying considering how much easier other companies have made it for their cubes. It's not that bad though, and I haven't broke any of the plastic pieces on the magnetic tool like I've heard other people have and I was worried about.

If anybody's interested I currently average 13 seconds on 3x3, and I set this up similarly to how Matty Hiroto Inaba said he set up his Gan 11 M Pro in a comparison video.
-Angstrom Gravitas on 2 adjacent edges, 2 "Globs" of Mystic on 2 adjacent corners, and DNM to preference. I used about two drops of DNM overall.

In this configuration this is actually one of my favorite cubes that I own, and it's cheaper than the cubes I'm choosing this over. Though, I got it when it was labeled a bit cheaper. (Before they released the Lite version). So maybe consider that version as well now, if the added accessories aren't worth the extra price for you.

The cube is good and very fast, however, it is somewhat hard to control out of the box. But this cube is still very good if you want a really fast cube.
Also as a side note, the cube is slightly smaller than another 3x3's.
