Product review (5 stars): but it looks like we're going to tie it into the water supply ...
I debated getting this or a countertop model for my small kitchen, ending up buying the portable rolling dishwasher. I use it for a family of five, and it perfectly fits our needs. I underestimated how deep 18" would be, so I had to get creative about where to store it, but it looks like we're going to tie it into the water supply for the washing machine (it's in our kitchen), so it worked out better, anyway.
The dishes came out soaking wet before I bought and added rinse agent, so keep that in mind. Other than that, this thing takes a couple hours to complete a cycle, which isn't ideal for daytime use, but is perfect over night, and will be great once permenantly installed.
Also, hooking up to the kitchen faucet is a breeze. Truly happy with this purchase, overall.
