Review on Advanced Structures For Babies & Toddlers Ages 10 Months And Up - WEofferwhatYOUwant Super Ball Drop With Double Bridge & Spacers! by Dustin Wright

I've been looking for a marble run like this for such a long time, I don't know why they aren't more common. I have a 4 year old who loves toys like this but a regular marble run would be a choking hazard.This toy is absolutely perfect, the balls are a perfect size for younger kids and the track itself provides complex enough movement to keep the kiddos entertained without being too complicated for them to assemble.And the balls are a great touch, they are transparent with multicolored beads that make noise as they roll. Very entertaining, I think I like playing with this as much as my kids do.I'm very pleased with this set, my only complaint was that I would have liked a bigger set with more variety of tracks than the pink and purple pieces to be available for purchase.I bought two of these to make larger constructions. No regrets!
