The DianSheng Petaminx is the first mass produced magnetic petaminx puzzle and it certainly performs much better than any other petaminx on the market. The Petaminx is a 9x9 minx puzzle, speedcubers use the metric prefix system to denote the size of the minx puzzle, from the regular 3x3 version being the megaminx. The Petaminx is the largest minx puzzle that is currently available in a magnetic version but DianSheng probably plan to release larger ones in the next year or two. I am quite pleased that they haven't increased the price too much compared to their Teraminx, I will probably stream a solve of this at some point, how long do you think it will take me?
