### ⭐⭐⭐⭐⭐ Awesome Product
*by K***. on April 7, 2017*

My 4 year old (almost 5) absolutely loves this K'NEX set. He's young so initially we had to help him learn to follow the instructional and help him snap pieces together, but after about a month he can now do most of the designs completely on his own. The instructions are different from Lego's in that they show a natural progression rather than going step-by-step, but if a 4 year old can figure it out then I think the instructions are pretty good. I love this set because kids can make so many different things; so far he's made the flower, swordfish, airplane, jellyfish, picnic basket, high dive, windsurfer (my personal favorite because it moves). This is an incredible bargain compared with Legos. I also appreciate that it helps him think logically, learn to follow instructions, and develops fine and gross motor skills. And it keeps him totally entertained for 30-60 minutes. Amazing toy at an amazing price. We'll buy more.
