Looked good

Bought for grandsons birthday He loved it

It actually walks!

Bought for my 6 year old who loves Knex. He was able to fix it all together but it wouldn't walk. Hubby rearranged a couple of bits and got it walking which 6 year old was very happy about. So younger ones may need a hand. Great toy for logical play (constructing) and creative play.

5 / 5

Brilliant Set

Great set as expected from my experience with other Knex sets. My six year old son loves building and playing with it and likes taking it apart to build again. Build quality of Knex components is great and set comes with easy to follow instructions.
