It's easy enough to assemble but also easily broken apart. Could be a little sturdier as I guess my 3 yr old tends to place cars a little tough because i'm constantly putting it back together. Does not work with legos or Dublos. That said we are enjoying playing with it.

My 2-year old granddaughter loves it. Funny story…her mom worked hard putting it together exactly as it was pictured. She put it together in the living room and dropped it on the way to my granddaughter’s room. They had fun putting it back together. I only recommend this toy if you enjoy lots of tiny pieces and enjoying Lego building.

The instructions were not lego level clarity and after you get it all together you start to realize it's almost impossible to build a STURDY functional track with it but it was good enough to keep for the kids.

The feature that makes this better than a regular Lego or duplo set is the winding tracks with the little cars and emoji balls.My Grand daughter loves it.

5 year old birthday present.. helped her at the end to put the ramps up.Had to modify it a little so cars would Roll better.. she loves it and her little brother would get so tickled every time the cars an balls come down the ramp ..

My 3 yr. old granddaughter loved this, was a little project with her father ! She played with it for hours, she made it after all.

We liked this product but they come apart REALLY easily. Followed the instructions but I think they are wrong because it doesn’t seem as sturdy as it should be for the cars and balls to go down then ramp. My daughter is very gentle with her toys but this thing comes apart literally every single time she plays with it.

4 year old grand daughter got this for her birthday. She loved putting it together with her daddy and plays with it all the time.
