Fits with duplo
I really like them My kids play the slide every day. Dinosaur eggs are really well made and fun to play ONLy thing is that instruction is very complicated.

Quite well designed... the marbles stay in motion for a long time
This is a mature product. The marbles spin for quite a long time in the cups/dishes/hemispheres before dropping through the center. The little track with upward-curved ends allows the marbles to move back and forth before rolling off one side. Both my kid and I like it. The last marble run that I used was made in the 1970s; this is much improved. A child might not be able to build much with it until the age of four. My kid is a bit younger than this and can combine components to make objects, but not paths. She enjoys playing with what I assemble, though.

A very nice block set.
This was a Christmas present for a little boy. He opened today and he loved. Strudy and can be used with Duplos.

Lots of fun for my son!
My 4 yeah old son loves these. He will play for hours! The blocks are built like the big Legos and are easy for him to put together and take apart. He has tons of fun. I give it 4 stars because I feel it needs to come with more building pieces. They is only so high you can make it because you run out of blocks for the base but still have a ton of track left over. Some of the base blocks that came with ours where wonky and don't fit so they ended up being useless. Despite that though it was still one of my sons favorite Christmas presents he got this year.

Terrible product!
Horrible child's toy. All the building blocks were not there and it was hard for the adults to connect the blocks let alone our 4 year old granddaughter. The stickers also did not fit and took forever for us to put them on the one apple block, thats what we think it was. Because we bought it for a christmas present in October, the return time was expired in November. Now we are stuck with this horrible toy. I will never buy from this company again.

Lots of blocks, cute animals, blocks don’t stick
I like the amount of blocks that come with this. Then, the animals were fun to build and decorate. They were really cute. However, the blocks come apart very easy. This makes it difficult for my 2yr old to play with them. I wish they stuck together better. I would’ve went with a different brand had I of known.
