Assembled the K'Nex Supersonic Swirl building set this morning only to find a few pieces missing.
1 purple arm
3 black arms
2 red transition arms
4 blue spacers
1 light grey connector
Emailed customer service so hopefully they will send the missing pieces quickly.
This was our first K'Nex set (after years of LEGO sets) and I have to say the instructions are really lacking in clarity. More than one connection was made wrong because the graphics were too condensed or showed the connections from a bad angle.
