Product review (5 stars): Arrived Quickly and As Described
While I wasn't crazy about the price given we'd just shelled out $300 for the dishwasher, they mounting brackets worked well and were easy to install.  Like many people these days, we have granite coutertops, which means no undermounting unless there is a backerboard or something on your granite.  Thus we needed these, which were not included with our GE dishwasher.  I'd recommend them if you are in a similar circumstance.
