The Moyu AI Cube does not have a magnet strength adjustment system, but the Moyu Weilong WRM 2021 does. The sizes and colours of the two cubes are practically speaking identical. So I swapped their pieces and got this. I did not swap the centre caps. Does it work? Yes, everything including the smart features worked as before. The main difference is that the smartcube gained 2g or at most 3g (with some stickers). The normal AI Cube weighs 80g. The enhanced smartcube feels about the same as before. Its magnet strength was a little too weak for me before but I can adjust it now. I set it to the strongest "1" setting and it seems better, fine, now. It also seems a little bit quieter now.
The Moyu WRM 2021 is now essentially just a Moyu WRM 2020, without the magnet adjustment system. Still a good cube, and so similar in feel, so it's fine as a backup or for when a smartcube is not needed, or when it's being re-charged, or when it's not allowed (like in comps). Updates later after more use.
