Review: A Good Introductory Set for K'NEX - I bought it for a 4yo and he loves it. The set is generous with the pieces so you can build about one 3D model (e.g. ambulance) and one 2D model (e.g. turtle) at the same time. I'm planning to order 40 extra green rods and 10 green connectors (135 degree shaped) to add more versatility to the set. It'll cost about $10 extra (because of shipping), but I think it's better than buying another $30 set and having an even greater shortage of green rods. I think there are two reasons why this set is marked at age 7+. First, most of the designs do not have instructions. So you need to use a magnifying glass to see the examples in the instruction booklet. There are designs on the K'NEX website which are nice too, but they use a white background so you can't see the white pieces well. Again, some squinting and spatial intelligence is required to figure it out. Second, attaching a rod perpendicular to a connector requires A LOT of dexterity and strength. I broke a piece trying to snap one in today and the shrapnel hit me in the face. I would rate it about as difficult as unscrewing the lid from a jar: some people will not be able to do it no matter how old they are. I think K'NEX is better than Legos, particularly for this young age group. With Legos, you end up making 1-3 designs (see their Creator series) and then you're done building them forever. K'NEX allows much more variation and adaptation to your design. For example, if you spent over $200 and bought the LEGO Star Wars Millennium Falcon 75105 Star Wars Toy you could only make ONE cool thing with it. In contrast, you could make a similar-sized Millennium Falcon with K'NEX with about $70 worth of pieces (and probably every other model in this set). The trade-off is realism vs versatility/playtime. With this age group, versatility and hours of playtime are going to win every time. Once they're old enough to have a credit card, then Legos and Bricklink become an option. But by then, can you even consider Legos a toy any more?
Review: Knex’s is one of the greatest building toys ever. - Knex are absolutely the greatest. It can take you anywhere with your imagination and creativity. You can build anything. The pieces are sturdy and fit together well. It is absolutely amazing what you can do. It will give you and your child hours together which build better relationships and wonderful memories. The challenge creates a real sense of achievement when you finish a project. it’s really more than just a toy. It creates so many wonderful things other than the projects, memories, Togetherness, cooperation, understanding, problem solving skills and even goal setting just to mention a few. Plus it’s great no matter what your age, it’s great for people who like to build models. I first started to do knex with my son. We loved it, we had most of the sets back then and built fabulous things together. Our biggest one was the Ferris Wheel that was motorized. It took weeks. Now I am doing knex with my grandson. It brings back such great memories for my son. He is so excited to be doing knex with his son.

## Questions & Answers

**Q: Does the kit come with a book containing all 100 design ideas?**
A: Only a small photo of about 90 of the design ideas are shown on 1 or 2 pages. Only abut 10 of them are shown in details and with step by step instructions

**Q: Does this product contain assembly tools as well as parts?**
A: No tools needed for assembly other than hands.

**Q: Are there really 863 pieces?**
A: I believe the MRSP for the K'NEX 375 Piece Deluxe Building Set  is lower than that of the K'NEX 100 Model Imagine Building Set.  Each Amazon seller sets their own price level, so I am not able to explain the difference that we currently see.  I hope this helps.

**Q: Has anyone had success in contacting K'Nex about replacing broken parts? Is there ant value in obtaining the warranty?**
A: Contact K'NEX if you have missing, broken or defective parts from a new set.
