Kids Marble Run Building Block Dinosaur, Montessori Learning Resources STEM Toy Bricks Maze Puzzle Set Race Track Compatible with Major Brands for Age 3 4 5 6 7 8+ Boys Girls Birthdays

My soon to be 3 year old LOVED this build! Instructions were easy to follow. He could help me find a piece and but needed a little help to install it. Great quality product! Lots of learning opportunities (colors, counting, STEM, etc.) Because of the size of the balls, although bigger, it’s still a toy that needs to be monitored with young children. I plan to keep it in its box when not in use, so pieces don’t get lost or mixed with other toys. Many of the pieces are unique to this product. I would totally buy this again as a gift!

Good quality, assembly wasn’t bad except a lot of pieces. Good design marble run for young kids. Marbles are good size, not small. Grandson played for hours first day he received.

Atlas 4: I really liked it, and had a lot of fun. I built a lot of marble runs.Patience 7: They should have included better directions for the tower, but I figured it out. (Turns out the inside has to be installed a specific direction.)Great price for some quick, creative fun...my pre-k group at co-op loved it. Still working great although my Irish setter got ahold of the inside of the tower and we had to do a quick glue fix.

My son thought this was the most fun! The compatibility with the marbles, legos and contraction being his three fav things! value for money is great.Variety of pieces was perfect. Really easy to put together! The sizing was awesome.

One star less because they don't all fit with each other, but it is otherwise decent quality. Value for money? Not at the normal price, I got this on sale for Black Friday and I don't think anyone should pay more than 20 bucks for it.There is a fun variety of pieces, they don't all really go together which is part of why I don't think it should be more than 20 bucks, but they are cute. They also don't break when they get stuck together. It's really fun, however it is expensive for what you get under normal prices.

Really cute toy that sparks your child's imagination and creativity.

The product is nice, all nice colors, easy to assemble, not too big, works well but my box was missing pieces. The curved piece that connects the blue and green slide in the picture. My son was very upset after seeing that he can’t play with it. There was no option to replace the item, I had to return and buy again.

This toy is so very much enjoyed by our 4 year old grandson & 2 year old granddaughter! They both are enamored by the built in elevator that moves the marbles to the top, to roll them down again & again automatically.He has a fascination with the engineering of the movement of the toy, while she just giggles as the balls go up to funnel down. A true “keep them pre-occupied toy” :0) that is mesmerizing to look at with all of the bright & colorful plastic and the colorful marbles! A keeper for many years to come and well worth the cost!
