SPEED CUBE? PROFESSIONAL? My ass. This worthless cube sucks, and I'm giving it two stars ONLY because you could buy it as a gift for your child or a friend of yours that wants to take the challenge, but it is totally NOT recommended to speedcubers or to anyone wishing to have a fast cube, because it's not. Turn quickly but not smoothly and it's not magnetic, so I pretty much feel scammed by whoever wrote that illegal description
