It is rather strange how so many cube brands are in the process of releasing large minxes and it seems that ShengShou have forced YuXin to reduce their price this time too. YuXin are soon to release a master kilominx which will probably be the same price as the ShengShou one which was recently released.
Previously, YuXin have been the first to release other large minx puzzles but it seems that this time ShengShou have won the race and have a headstart in sales, I suspect this has forced YuXin to reduce the price, I hope it won't mean the quality is worse as YuXin's other large minxes have all performed better than the ShengShou ones so far.
