Dagu robot base with metal tracks (OddBot)

Hi, some minutes ago I read you were talking about a tracked chassis and then I remember that a week ago I saw this at Robotshop

Since I'm looking for a  tracked chassis, I just want to know if this is really from Dagu and if you have tested it, cause I was thinking on get the one from lynxmotion but this is half the price. I would appreciate your answer.
