Good toy that will entertain for many hours
This is a good toy that will entertain boys or girls for many hours. My only complaint is that the instructions that show you how to assemble it use different colors than the plastic pieces which makes it confusing for children. It has many small pieces so consider if it is appropriate for the child. Other than that it is a good toy and a good value.

K'nex 15th Anniversary Tub
I bought this product for my grandson's 9th birthday. He loves K'nex products. This was the perfect gift because you can use with existing K'nex products to make lots of different things. He makes buildings and cars. He even made a cellphone!! Great toy..great bargain...quick shipping!!

Slightly disappointed
I got this set to add on to the 400 piece value tub that I had previously bought. I was slightly disappointed in the number of model directions provided (8 instead of the 20+ that I got in the last tub). I am also not overly fond of the miniature k'nex and the bricks. I was hoping this set would more readily augment my previous set.

However, disappointments aside, this set is a good value if you understand what you are getting. I liked that it adds more varieties of wheels.

Not user friendly
Nice variety of models and good for developing fine motor skill. However, the instructions are very difficult to follow, even for an adult. Makes it pretty frustrating. There are no step-by-step instructions but rather about 2-3 pictures per model showing lots of different steps in between. Not what I expected but if your child likes creating his/her own things then it would be a good toy.

Great Building Toy
My nephew loved this gift. You can build cars, planes, building, animals, and any other things a child can imagine. You can combine with other K'Nex. Nice to have a case to store the parts.
