Ordered 3 sets and received them today to convert a few non-maglev 3x3 moyu cubes to maglev. Checked with my caliper and the size is identical to the magnets in the moyu rs3m 2021 maglev 3x3 cube. Perfect fit. Thank you!!! Still prefer the finish on the 2021 version better than the retrofitted 2020 but it is great to be able to convert all my moyu 3x3 cubes to maglev plus have extra magnets for spare parts in case it is needed later. Hope these continue to be stocked.

I bought this for my son as one of his Christmas present. When we opened it to install, one of the magnets were broken into pieces. He was a little bummed, will be contacting customer service.

Sadly this does not fit a gan cube

The maglev kit was super easy to set up in my RS3M and has been working super well, but after a bit of time I started to notice what sounded like spring noise. It seems like you'll still want to lubricate at least the upper magnet as it can rub against the blue retaining cylinder and squeak/create dust

Got sick of spring noise and the red side always being harder to turn then the rest. I was about to upgrade to the RS3 M 2021 but then I found this kit on your youtube channel. Installed these as well as some DNM-37 lube. It's completely refreshed my RS3 M 2020. It's soo satisfying just to play with. I've been practicing a lot and improving. I

I decided to save $1 and buy this kit along with a RS3M 2020 instead of buying a RS3M 2021. As best as I can tell, these magnets are identical to the ones in the RS3M 2021 so if you want to save a $1 and don't mind fully disassembling and reassembling a cube, it's not a bad purchase. I'm half tempted to buy another set and try to add 1 or 2 magnets to the centers of another RS3M 2021 to see if that would do anything productive.

Given the cube has metal screws going into a plastic core, I would encourage others to limit how many times they remove and reinstall those screws.

Unlike some other reviews, my magnets arrived undamaged.

The Cubicle team was fast and courteous with sending out the additional set of replacement magnets. I am very satisfied with the customer support.
The reason I gave 4 stars was that two of the magnets from the replacement set had a fracture line in them(One of them ended up breaking into pieces when it attracted onto another magnet).
That being said, my son has been very happy with his cube once he was able to install them.

I have a YS3M, and the maglev donut magnets broke when I removed them (they snapped together forcefully). So I needed a replacement set. These are great. They're are not exactly the same as the ones that come on the YS3M (these are a little thicker than the YS3M magnets), but they work perfectly, and my cube is fixed now.

Great to put it in the RS3M 2020

Worked alright, but a couple of my magnets came broken. I had to very tediously get them back together and make sure both broken pieces don't attract the other magnet.
