The MoYu Super WeiLong is MoYu's final (I assume) release of 2023, it is significantly more expensive than anything else they have previously released, out of the box the tensions are rather tight so I would recommend loosening them. It comes in 3 versions: a 8 magnet ball core version with spring tensioning; a 8 magnet ball core version with maglev tensioning; and a 20 magnet ball core version with maglev tensioning. All 3 versions come in a ridiculously oversized box! the box also features a watch strap which allows you to put the cube on your wrist and carry it around with you (I don't know why anyone would want that...)
