Product review (3 stars): Good idea, but only lasted 1-1/2 years.
These are a great option if you have the type of dishwasher that screws to the under side of the cabinet. The installation was extremely easy.  I had them installed for about 1-1/2 years before they let go.  I think part of the reason mine didn't last too long was because my dishwasher discharges the steam more towards the top (right under the grabber bracket) instead of the face of the dishwasher. The side where the steam comes out let go first, then the other side let loose a couple of weeks later.  Probably because there was too much pressure for just one side.  So I will be re-ordering another set.  For the price, and the amount of time they lasted, I guess I can't complain.
