Product review (2 stars): It's the only way to keep the dishwasher rack working
Samsung made these junky plastic bracket adjuster parts that wore out on our brand-new dishwasher within a year, while it was still under warranty. I knew I was in trouble when they sent me not two, but four replacements. Those lasted less than two years under normal, and not very heavy use, and with no adjusting of the rack once we got it where we wanted it. The adjusters have six little tabs to hold them onto the rack, and these tabs break one by one till there's not enough left to hold it in place. Samsung did make a slight mod to the later ones by adding a little teensy bit more reinforcement to the tabs, but they still broke in far less time than they should have on a moderately expensive dishwasher. Manufacturers are making junk these days at all price points. What ya gonna do?
