K'NEX Cyber-X C10 Crypto Crank with Motor - Blasts up to 60 ft - 383 Pieces, 6 Builds, Targets, 10 Darts - Great Gift Kids 8+

I've always liked K'NEX as a toy, but there's also something to be said for it's use as a rapid-prototyping tool. There's no cutting, measuring or gluing so adjustment is always just a snap or click away plus it's easy to incorporate gears, motors, and other mechanical elements. When I first saw the front image of the Crypto Crank, I had to see for myself if it really was a Gatling blaster...Well, I got my answer-it absolutely is!The lead build is honestly kind of insane-you mount it on your shoulder and rotate a handle, which spins 3 different gears. This activates a cam mechanism which pushes the darts out of the magazine in-between 2 motorized flywheels. The flywheels grab the dart and send it out the front chamber at hurtling speeds!The lead model in the instructions does take some time to put together, but there are also 5 other models that can be built from the pieces you get that are simpler to assemble. They all function very differently and you can even build different targets to practice firing on.Definitely worth buying and I know some young kids that may be getting this set or others from the Cyber-X line this Christmas!

I got this for Christmas for my 11 yo son. We spent a couple hours building it together, which was fun. But the thing doesn't work. I'm an engineer, so I'm pretty good at putting things together. We built it right. The motor runs, but doesn't pick up the bullets when you crank the handle. Don't know if I just got a defective one, or if it's a design flaw. Frustrating to give a gift, spend hours building it, with my son looking forward to using it, only to find out it doesn't do squat.

Spent hours building it, but finally got it together. The instructions were good, but not very sturdy. Entertaining for an afternoon but that is about it. Handle falls off constantly. Would not buy again.

Got this for a Christmas gift for my son, we spent hours putting it together for it to not even work. So disappointing

I bought this item as a gift and the child just loves it! He had so much fun building it and even more fun blasting with it! He was so exited to see that you can take it apart and build other designs. HOURS OF FUN! I just purchased another one to donate to our firehouse toy drive.
