Best chain reaction set
Super fun, kids ages 7 and 3 love making chain reactions and building with these. I love that keva planks are cut so precisely, they balance effortlessly.

Creative toy - no batteries required
Was given as a gift to a 10 year old boy. 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.

Fun building set for kids
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.

Great fun for 6-year old ... and his Dad!
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 son loves these
This is the second Keva plank set we have bought. My son constantly builds towers with these planks. He’s not that interested in building what’s recommended in the manuals yet. He let’s his creativity flow with these. Our whole family will work with these and it’s rare to find something everyone can enjoy.

Hard to make the pieces stay together
I bought this for my classroom, I teach science and engineering, it looked so cool in the picture however my students find it hard to build things that stay together and they are easily bored by it. The quality however is excellent. Maybe someone older than 9 and 10-year-olds would like it better.
