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.

Creative play
Great for imaginations! Can be a little difficult to build so you need steady hands, I would say older kids 5/6 years +

Avoid
Well made and packaged but essentially this is just a box of bits of wood that requires substantial effort to create a somewhat pointless outcome. Worse still it’s very expensive.

Grand sons favourite - many possiblilties
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 !
