Very happy with this purchase
The grand kids are enjoying from the 3 year old to the 12 year old. Holds the track very well. The night racing is really cool and the remote controls permits the kids to move around while playing.
Be sure to read the instructions. Also, after putting it together, a couple connections needed a little tweaking but wasn't a big deal. The cars are holding a charge pretty long.
I read a couple of negative reviews on Amazon which gave me pause but I'd definitely give it 5 stars.
I learned about SkullDuggery thru a CNBC satellite radio segment of the show "Profit". Glad I caught the show.
