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?

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.

Buy 2!
I bought two during the prime sale. I bought the set for my grandchildren. 6-year-old did well. 4-year-old had limited attention span but still played with it. Great thinking toy with multiple building options. I did these with my daughter and the neighbors when they were little. The science museum had an interactive exhibit at that time ( >20 years ago). I would recommend placing small parts in zip lock bags as you open the packages.

the booklet needs some work.
I bought it for my 6 year old daughter. (i know it' meant for 7+) My observations: 1) Making certain connections or disassembling some connections is PHYSICALLY too difficult and perhaps even impossible for a girl that age.Connecting some assembly and disassemble is too hard for that age 2) supposedly there are 100 ideas but the booklet gives detailed instructions for only about 10. The 90 or so ideas were shown as a small photo 3) the first model in the booklet is a 2 dimensional bus and my daughter picked up the principals very quickly, however, there were no more easy 2-dimensional model instructions. The next thing was a complicated 3-dimensional model. My daughter was very excited about the completion of the bus model but then when i showed her the next thing she didn't want to even start it because it's orders of magnituded more difficult. The booklet should have more progression in difficulty of the models. 4) The instructions are not accurate. It's impossible to build the Eiffel Tower based on the instructions in the booklet. That was very dissappointing at first. we didn't know how to connect the 4 legs to the body. i showed the instructions to several adults and no one was able to do it the way it is illustrated. Finally we improvised and it came out nicely. i can attach a photo of how we ended up connecting the legs if anyone is interested Overall i think it's a good product. if the booklet had more detailed instructions for more models, progressing gradually in difficulty, it would be great

Great set for those who love to build things
I love to build things and K'NEX us now my favorite system to do this with. I now have 18 different sets and over 8000 parts to play with. I really appreciate their on line instruction manuals as they have great build ideas. I just realized that the hole in the bearings of the Ezoon spinners is a match for the rod size of the normal K'NEX sets. This lets me incorporate figit spinners into the constructions I make. I have a ball machine set on order and am thinking I can add the spinners to the design at some point. I realize some people don't like mixing set, but I enjoy it when different items mix well and add to the things you can build. Maybe i should mention that I am a 71 year old kid when it comes to construction sets and I recommend this set to anyone who likes to build things.

実家で子ども達が遊ぶ用に購入。 中学生の娘が何時間も集中して色々作り、小学生の息子も楽しんでいます。集中力がとても養われ、達成感も味わえて、子ども達は喜んでいます。 説明書も付いていて、作りやすいようです。

Jeu extraordinaire qui passionne mes 3 petits-enfants ! Contrairement au lego , on peut faire des modèles à l'infini en allant sur le site de Basic fun ! Je vous le conseille fortement rapport/qualité/prix très remarquable !👍🥰

There are many examples the kids can choose from. More than one child can play with it at the same time, either building something different or together building something more complex. They can play with it for hours while you do something else. Not foe very young children though, it contains small pieces. It is a great educational set that challenges their creativity.

小学3年・1年の娘向けに購入。はじめは説明書見ながら真似してましたが、慣れてきてからは自分で自由に繋げて楽しそうに遊んでます
