I do have to congratulate Mini Mania on slick packaging and good marketing. Some people certainly like the feel of the more aggressively mapped pedal, and the fact that they are able to sell these at this price is impressive. I'm sure there will be a Taiwanese knockoff hitting the streets in a year or two for $99.
