Marble Runs Dinosaur Adventure with Gravity Hammer and Building Tracks, 80 Pieces Compatible Construction Toys Interactive Ball Tracks Maze Game for Kids Ages 3 4 5 6 7 8 Years (Dinosaur Marble Run)

Love this set. We got a dinosaur set from the same company before this and wanted more pieces. Well thought out design, pieces fit well together and with duplos. Overall I'd say this is more fun than normal marble runs and has kept 2 yr olds through adults entertained for hours. I bought a similar set from a different manufacturer and immediately returned it due to how inferior it was to this product - no joke we actually took it away after giving it to our kid.... And immediately went and bought this one.

My grandson loves to watch marble runs so I got this for him when he was three. Its a great set and very entertaining but I think it was a bit advanced for him as he did not know how to use the part that shoots the marble forward. I think it would be great for a four year old though. Very nice set, well made and good value.

It’s cool, but I thought is was several “sections” that could be interchangeable. It’s a full Lego type toy with many parts and pieces. Instructions are difficult to follow and will take a few years before my 5 yr old grandson can fully enjoy.

This is my 3rd box within 2 months. The pieces snap together like LEGOs, snug fit. The marble runs are fun and unique. I bought 2 boxes for my daughter and 1 box for my nephew. The box come with unique dynamic parts that make the marble run a bit more interactive. Enjoy!

Spent about 20 -30 minutes putting together which is OK, but 3 year old took half of it apart and rearrange pieces. Understandable since it is made of legos.Step by step instructions are good, but they do not create the science depicted on the box!I went to the support website and received 404 page does not exist error.It appears you could configure the run differently but too challenging without directions.Also the box implies you marbles will run over and overThis is not true as you must reset the swinging ball bearing after each run.In conclusion, although the three year olds LOVED this adult intervention was constantly required. So the claim that this is for 3+ is a a bit questionable.My biggest frustration is that I cannot find directions to build the scene on the box. A website where I could access a pdf of the directions would solve my concern.

We bought for a Christmas present for our 2 1/2 yr old. She loves it. There are so many ways to put this together. They give several diagrams for options. My husband and I came up with several of our own. We want to buy extra pieced to create more designs. The negatives: like Legos they come apart easily so it's easy to have and accident disconnecting. Also not many options for a continuous flow of marbles. You do have to reset thr launchers each ball. We did find a few ways to make it sort of continuous not using those pieces.

This set integrates really well with name brand Duplos and other off brand sets, it adds great variety to other marble run block sets.Pros: marble launcher is a great novelty, the dinosaurs are really cute and integrate well in the runs. Comes with a good amount of ballsCons: the dinos are sized so you need half height blocks which are provided, but it can get frustrating making intricate tracks. Some of the dinos aren't sturdy to small boys who launch everything, I've had to super glue 2 dinos so the jaws stop popping off into their 4 individual pieces

The item does not work, nor is it kid friendly. The marbles do not stay in the rails, they jump out of the track. The marbles do not always make it back in to the tower. The button to launch the marbles does not always work. The parts do not always stay together. The instructions/construction need need a LOT of adult supervision. I would return the toy, however, once you give and assemble a toy for a three year old, its difficult to pull it away from them. Purchase a different toy. Thank you.
