Was well worth the cost ! So many ways to use he is constantly building something different . I thought pricey however solid high quality and excellent alternative to his Lego !

Was given as a gift. He loved building and creating with it. It has a lot of materials in a small box. Was surprised when he created a domino run almost 12 feet long.

Why did you pick this product vs others?: Requested by 6-year old Grandson. He and his Dad have been working on it together. They've been having a lot of fun with it. He's beginning to build it on his own now.

My grandson age 9 played with this most of the day when he got it for Christmas.

My 11 year old started building these blocks at his school and I decided to get him a set for his birthday. He is having so much fun with it. And I am glad it keeps him away from tv. Quality is great, it can be used in so many different constructions. Totally worth the price.
