Bought this for my daughter as a Christmas present. She had a great time putting it together - took her about 2 days off and on. Only issue is that the track sometimes detaches from the hooks causing either the chain to get caught or the cars to get lodged between the tracks. Minor tweaks gets it going again, but re-occurs often. Have to admit though... it did keep her focussed for the 2 days it took her to build and beyond with the minor repairs.

I purchased the K'nex Atomic Coaster for my son who has a ton of patience and enjoys building and problem-solving. He has generally enjoyed building sets, and I'm patient and engineering-minded. I thought this would be a fun challenge for us to tackle together.

Unfortunately, both his patience and mine were sorely tested by this product. According to the box, there are 1255 pieces. We had about 1260 -- there were extras of some pieces, but unfortunately, a couple of pieces were missing as well. (Just sorting through and counting the pieces prior to construction took well over an hour.) I managed to fabricate replacements for missing pieces, and we began assembly.

The instructions here are pretty painfully difficult to follow. A typical contruction step (and there are 83 of them) might involve 15-20 pieces to be connected in ways that can be difficult to ascertain from the too-small illustrations. Frustrating.

We finally finished (about 9 hours after opening the box,) and at first my son and his brothers were delighted. This was short-lived, however. After they played with the coaster for an hour or so it is no longer functional. Several of the plastic connectors (especially those that support the track) wear down after use and fail to remain clamped. (A couple of these pieces are specialized and can't be "switched out" with a similar piece from elsewhere in the set.)

The pieces are simply flimsy and cheap, and so long hours of difficult assembly are "rewarded" with a relatively short play window before the set is ready for the junk pile. I'm sorry I purchased this, and my son is disappointed that our project is already "broken."

Amazing Roller Coaster

By Homeschooldrmom

from Calgary, AB, Canada

Comments about K'NEX Building Set - Atomic Coaster:

My 10 year old son was given this Roller Coaster for Christmas. He and his oldest brother immediately started building it. They had so much fun working together and it only took them about 30 mins. He loves this Coaster and still likes to play with it.

Impressive Double Coaster

By HOps

from Calgary, AB, Canada

Comments about K'NEX Building Set - Atomic Coaster:

My 9-year-old son loved building this one. The chain and gear mechanism was a bit finicky though - one cog was catching on the track. He managed to fix it with a little help from his dad.

troubling

By nicknak

Comments about K'NEX Building Set - Atomic Coaster:

I got this for Christmas and attempted to build it the hooks or connecters are very painful to your fingers and I would often find the some of the pieces are missing in the end I ended up giving up because of the instruction manual being hard to understand , would not recommend this set to build alone.

Very disappointed

By Pops

from Undisclosed

Comments about K'NEX Building Set - Atomic Coaster:

The top front of the rail and support pegs can't hold the track up.  The yellow peg and track guide keep popping off which causes the chain to get caught. Very frustrating. This one major issues prevents the motor from running properly which ruins the whole set.
