i've been wrenching for 30 years, started out with kennedy mechanics boxes, as i added more tools, i added more boxes, mac, matco, and snapon
mac & matco had quality problems with their paint,
i witnessed more than one box literally fall apart , broken welds, really crappy friction drawer slides.
when i decided to buy my 1st big set of boxes in '86, i bought a SO KR550/555B set.
for working boxes,
I wouldnt consider anything else.
garage/home use is a little different.
no wait
i have SO boxes at home as well
