Product review (5 stars): Quick install and worked well.
We are temporarily moving into a smaller place while we construct a new home and planned to stack our existing washer and dryer to fit in the space we will have available.  This did not take very long to install and actually took longer to remove our drawer stands.  Be cautious of the sharp edges with the metal slots on the back of the appliances while installing it.

The dryer has been stable while both were running, but I also chalk that up to making sure to level the washing machine on its intended place prior to installing this.
