Have had this handleset installed in a new home for less than a year and the interior knob kept falling off. The interior mounting plate does not have full through holes for the bolts to fasten to the exterior knob. Instead, there are notches that allow the interior mounting plate to rotate (opposite of install direction) and slip off of the mounting bolts. The interior spindle also seemed offset from where is should be and made the latch bolt sticky. Unfortunate, as I actually really liked the Hawthorne style.

Ended up replacing with the Kwikset Montara and so far it seems to be a much better mechanical design.
