We purchased this for our son who just turned 11. He loves to build and he, his brother and their friends are always making targets and playing around shooting nerf guns. He couldn't wait to build this and start playing with it. He loves it. All the parts were there, easy instructions and it works fantastic too.

Load a dart, pull the handle back, aim and shoot!
Interesting but slightly complicated to build

Slightly more interesting than a regular Nerf gun but too much play will knock something loose and it takes time to load each dart and pull the handle before shooting.

    K-Nex products are educational and fun. It keeps the kids busy for hours. They are always proud of what they have created. Good product but not for small children because of the little parts.

          Comments about K'NEX K-FORCE Mega Boom Building Set:

          My 11 year old boy loves nerf guns and legos found this product to be the best of both worlds. He said it was way better than a nerf gun because he can disassemble and reassemble, and there are four or five different variations to build so he really loves it, and the darts shoot harder and further than the nerf guns.
