K'NEX Thrill Rides Mecha Strike Roller Coaster Building Set

My 26-year-old started assembling this with his 11-year-old little brother. First it looked challenging that was a lot of fun. I can't believe how balanced everything is! It works through charm as long as everything is connected and set up properly. It truly is a piece of art!!

This is pretty cool. Even though I spent hours putting it together, my son loved it. It was a Christmas gift for him. The pieces are snug, so it doesn't come apart easy web putting it together. I would definitely recommend this to everyone.

Grandson saw the model at Walmart already up. He will be so excited Xmas morning!

This was fun for 2 of my middle girls to build. They don't want to take it down.

Missing pieces when we opened it

K next should be a shamed of their company.I brought 3 of these for my grandkids for Christmas and not one of them had all the pieces.I returned them and then still went and brought a different roller coaster one and them too were missing pieces.We even tried putting them all together to at least get one working and that didn't even work.Very disappointing for me and the boys.

I bought this item as a Christmas present last year for my grandson. it took us 3 days to build and with sore finger tips from snapping pieces together. it would not work right had to adjust the chain several times but never got it right. Don't waste your time or money on it it's just not worth the aggravation!!.

It was missing 3 tiny pieces. we had to find them from other Lego n Kinex boxes we had. Not good when your kid spends all day in building it n almost at end, there is pieces missing. All that hard work.

This toy is a piece of junk. you spend hours to put it together, parts to stay contented for long. waist of money and time.

Waste of money. Missing pieces. Pieces won't stay together.
