Just tried a prototype of the upcoming Vin Megaminx (yes the 4x4 brand) in a comp earlier today, it comes with frosted/UV coating, and the edges look very similar to the very old MGC Megaminx or the old MoYu AoHun Megaminx with the thick ridges. The grip is nice especially the UV version. But it is much smaller than the old MGC Megaminx or the old MoYu AoHun Megaminx, similar to the size of the GAN Megaminx V2. The prototype I tried is not lubed, and does have some tiny catches here and there. I assume it to be core magnetic, and I think it can be a good contender to be one of the best mid range Megaminx along with the YJ YuHu V3 or the DaYan Pro V2 Megaminx. Compare to these modern Megaminxes, the turning style is more similar to the YJ than the DaYan, with a slightly more rounded feeling. Whether it is comparable to the GAN Megaminx V2 would require proper setup to make a fair comparison, but at least for the prototype Vin Megaminx I tried, the GAN Megaminx V2 is still a clear winner with a more superior performance OOTB.
