Re: Remember the electric screwdriver
The last things I assembled from IKEA - two identical corner desks for the grandkids - both had a component with half the holes drilled 180° out of alignment with the other half, presumably either a half turn missed in the programming or an extra one inserted. One duff desk might have been an accident, two suggests a whole batch were out. That's the thing about consistency based quality - you swap the occasional rogue error for a job-lot of junk.
