Product review (5 stars): Our dishwasher was installed under a beautiful granite countertop
I've been using this for months.  It works just as specified.  You would never be able to fully comprehend the need for such a device until you do.  Our dishwasher was installed under a beautiful granite countertop.  as such, every time we opened the dishwasher door to load it, it would lean forward and both trays would slide out.  If you install this just as they recommend, it works perfectly!
