This thing is ancient now but used to be the best. Its mechanism resembles no modern speedcube as those are all descendants of the dayan and its guhong line from years back, but before that this was a world record setting king. It moves very fast and very very crispy and loud, cuts corners as well as it needs to. Not to much flex to it but none of these older ones ever really did. Its biggest downfall is popping, which in modern speedcube world practically doesnt exist. This still has its place in speedcube history and belongs in speedcube hall of fame. Shame it cant even hold a candle to the cheapest of new speedcubes.
