Countertop dishwashers are popular with apartment dwellers. They're small, inexpensive, portable and don't require the sort of plumbing work that would forfeit a security deposit. While compact appliances generally get positive user reviews, there has yet to be any independent, scientific tests of their performance. Until now.
We purchased a SPT (also known as Sunpentown) SD-2201W and put it through the same rigorous tests we use for full-size dishwashers.
