My wife got this for me as we love Rotisserie Chicken.  It assembles quickly, however it has a Factory Default.  The adaptor (#3 in the instructions) expands with the Neck Flange (#4) causing it to seize up.  This makes for some very one-sided chicken.  It is easy to fix if you have a Dremel Tool or something similar.  You will have to grind the shaft of the adaptor and inside the Neck Flange and a little bit of the face of the adaptor where the Spit Rod goes in.  I also, just for an added bonus, put a little Crisco on the the two to act as a lubricant which seems to work quite well.  And yes I tried that first before grinding.  Over all I really like the kit and feel that it's a worthwhile investment.  Just wish they would fix that part and I could give them 5 stars.
