(More customer reviews)My 4-year old son was upset with me last week cause I forgot to say goodbye to him or something silly when I dropped him off at daycare. To make it up to him I searched for some project we could do together and found this. Obviously it's way out of his age-range but he LOVES coasters and puzzles so I gave it a shot and it didn't disappoint. We built it together in about 6 hours, mostly it was me reading the excellent full-color picture instructions and telling him which pieces to find/connect and he got the hang of it quick. Seeing the final result and switching on the motor was very rewarding for him and he's telling anyone that'll listen about his coaster.
I'm giving it 5 stars but there are a couple things to be aware of with this model:
1. As stated in other k'nex reviews there are no extra pieces, be careful to not misplace anything, some are smaller than your fingernail. We ended up with one missing piece and a handful of random extras. I found our important missing piece by going to the store and picking up some little $3.00 K'Nex gizmo that had what we needed.
2. Why did they put two different black pieces in the same bag? The 100 or so chain links are mixed in with about 8 other black pieces of the same size. Arg...
3. Putting the track together is most frustrating part - track pieces need to bend and typically connect to main model with one tiny connector that often can't handle the strain until the full track is assembled. Once done though it's not a problem. My son was thrilled by the loop.
4. The chain - I swear I used the recommended number of links but I had to adjust it a little cause it kept slipping on the gear attached to the motor and falling out of the guides on the track. It still slips a little when hauling the cars up the track.
5. One of the cars inexplicably is faster than the other - so eventually it hits the other one just going up the chain and misses the chain itself. Oh well.
One nice thing is you can go online to [...] to find another plan for these parts, though it appears much smaller than this model. Since this is considered new in their product line I hope they publish more build plans.
I plan on getting more of these - it's fun for me too. :)
