Personally, i like them alot. I've watched a few locals with them, and they do good on the track. I've seen one friend we race with, beat his incredibly hard. Indoor, and outdoor. I've heard complaints of durability issues, but im just not seeing it. I've also driven this guys truck, and really liked it. I wouldnt hesitate to buy one if i were in the market for another truggy. The SS looks to improve on the original as well.
