Product review (1 stars): Crap product, shame you NEED to have it...
I hope this doesn't reflect badly on the seller, as the product shipped quickly, but these pieces are junk... They are cheap plastic and break easily under regular use. We don't overload our dishwasher on the top rack, and the tabs that hold the wheels on still break. We have had it for 2 years now, and this is the fourth set of these we had to replace. Whirlpool really screwed this up.... They need to make these things out of more durable plastic or come up with a  design that doesn't stink....
