Heh heh heh! Tell them you don't want one that was put together at quitting time on a Friday before Holiday!!!!
Would LOVE to hear WTH went wrong with the first one,,, We all know CHIT happens, but was the "upper cog placed on the lower shaft" at the factory,,, maybe a "shifting-related disaster",,, or,,,???
(I have a strange attraction to mechanical chit that got TORE UP BIG TIME unexpectedly by the 'yet-unknown',,, Kinda like a mechanical version of 'crime-solvers')
