Product review (5 stars): Perfect
This may pan out (pun intended) to be a great purchase.  When your dishwasher leaks slowly your screwed.  Your floor is rotted and you don't know till your dishwasher is in pieces on the basement floor.
With this you will see leaks before they ruin anything and obviously it protects the sub floor.
Installs really well
Fits perfectly
Very happy I bought for our new house
