what's not to like?
Fun!
M. Tennant•February 19, 2018
Bought this, along with the Starter Set, the Super Set, and several sets of accessories, for myself. Yes, I'm an adult. Yes, this thing is fun! Everything in this booster set works as described, except sometimes the red and yellow pieces in the photo let the marble go flying off. The end needs to be banked a little higher. If you slow the marble down a bit first, it usually solves the problem. The other pieces work great.
It's a really cool product and there is no real limit to how ...

Rick's wife here: I bought this for times when I can pry the grandkids away from their electronic toys.
It's a really cool product and there is no real limit to how you can set them up...especially if you get more than one set...which I did.

Great quality, and easy to use for young children

My son (5) is an aspiring contraption engineer, and absolutely LOVES this add on set. We are going to be purchasing more from this vendor for his next birthday.
