Rated 5 out of 5 by from Fun building toy My kids (ages 4 and 7) love building toys, so I was excited to have them try this k'nex building set. The pieces were easy for them to put together and take apart, which isn't true for other similar toys they have. I was glad it came with some pictures of things they could build, it gave them some inspiration! The set has a lot of pieces, but if you want your kids to be able to build multiple things at one time, a larger set might be a good idea (my kids didn't want to disassemble anything but still wanted to build more things!). Thanks to the weeSpring Parent Panel for letting us try this out!

Rated 5 out of 5 by from The new favorite toy in our house! My 2 and 4 year old sons both love this set! My 4 year old loves to make his own creations (usually consisting of microphones that he pretends to sing into!) and my 2 year old just loves to try piece after piece and see what fits together. Both of them love to help me get the pieces to build one of the designs in the booklet that comes with the set. I love that it keeps them busy and entertained and there are enough pieces that there is minimal fighting and I also love that there is a tub to keep it all in when it is put away! Thank you to the Wee Spring parent panel for providing us with this toy set!

Rated 4 out of 5 by from Fun for my 4 y/o Thanks to the weeSpring Parent Panel for providing me with this toy set! My 4 year old son reallt enjoyed playing with the K’NEX set. He liked trying to make the one suggested and also like making his own creations. We did have to help him with some of the rods and connectors since they were a little hard for him to get off/on. So this ended up being more of a toy for all of us to play with instead of him just playing on his own. The storage box was nice to keep everything in. We have a 1 year old as well so it is manatory for everything to be packed up so the little one does not get into it.

Rated 5 out of 5 by from Great Imagination Box Thanks to the weeSpring Parent Panel for sending me this building set! My 4.5 year old has been playing with it every night since we got it this weekend. At first she was really using her imagination and creating her own unique buddies but now she has gotten the hang of using your suggested buddies. I love to see what she creates. My biggest complaint is that there are not enough of the bending rods. I would love the kit to have included about a few more of the red and purple rods. I love that they came in this small green tub. Adding a handle would be nice for travel but necessary.
