K'Nex 18515 Mecha Strike Roller Coaster Building Set

This is a great set, but will require about 4-5 hours of time to put together. The instructions are easy to follow, and the pieces fit together well. But, this is not for a beginner at building sets.

Awesome! My roller coaster enthusiast, nine year old son LOVES this! I don't think he could have put it together by himself, but it became a fun family project. My three year old daughter also loves watching it go around! I think it may have become a permanent addition to our house.

I bought this as a gift for my son. About halfway through, we discovered that it was missing essential pieces. So we couldn't finish putting it together.

great for kids

I loved this, there weren’t many problems other than the chain is hard to put on, and if you don’t do it right it will snap it’s a lot of stress to build but it is worth it so you better be able to handle stress

Original packaging has what looks to be clearance stickers peeled off the original packaging. Box had been opened, and one of the punch out paper designs was gone from the punch out sheet. Didn't check the rest of the contents of the box as this is a gift for a child. Returned.

My grandson who is 8 just loves this set.

Bought for my 11 year old grandson. He had fun building, some of the small parts were a little tough to snap together. Hard on my fingers while helping him.Pro:Fun to build, instructions were easy to read. Fun to watch after buildingCon: had to download instructions for second build.
