Product review (5 stars): Great kit if you forget to include it into you online appliance order!
I purchased the cheapest Samsung front-loading washer & dryer from Home Depot recently.  However, I forgot to order the stacking kit so the delivery people were unable to install the appliances.  Amazon came to the rescue with getting thiskit delivered in time for me to reschedule the appliance delivery.

The kit was an exact match and the installers confirmed this was perfect for my washer & dryer.  Highly recommended!
