Product review (4 stars): So far, so good
We had a Danby portable (rolling) dishwasher for 5 years.  We liked the job it did, but it was a pain to roll around the kitchen, and when it needed repair after 5 years, we couldn't find anyone in the area who serviced Danby products.  After 2 years of hand washing, we recently bought a used Danby countertop dishwasher - which was a life saver until it died two weeks later.  So when we finally decided to buy a new Danby countertop model, we went in knowing that 1) these things don't last forever and 2) there is no one in our area who will service them when they fail.  We purchased a 4-year service warranty (through a third party) so that when it does fail, there will be some support.

All that said, we have so far been happy with this new one.  The wash cycles are long, but we have been using the rapid cycle (70 minutes) for everything, and the dishes have come out clean.

The manual gives a hilariously long list of things that you can supposedly fit in the dishwasher in a single load.  Realistically, for my family of 3, we can fit one meal's worth of dishes plus a few extras in each load (excluding pans, which we hand wash separately).  You will need to measure your space before buying, but for us, it takes up about the same amount of counter space as the dish rack, which we now put on top of the dishwasher, so we don't really have any less counter space than we had before.

With all of the Danby dishwasher models we have now been through, rinse aid is essential.  With traditional set-in dishwashers, rinse aid may be optional, but with the portable ones, the dishes just don't come out clean without plenty of rise aid.  It's not that expensive, and if you forget to fill up the pan, you'll see right away that it's not cleaning as well.

Finally, the dishwasher is packaged by Danby in a way that I'm sure is fine for sitting on the shelf of a store - but then I don't know of any stores that sell these off the shelf.  The packaging is really not padded enough for this kind of retail shipping.  The first one shipped was badly dented, and the replacement was also (less severely) dented.  We kept the second one with a price adjustment from the seller, and it's not so bad.  I hope that the packaging folks at Danby will consider this; otherwise, the vendors could add some extra padding and save themselves some damage returns.

All in all, we are happy with our purchase, and would recommend it - especially with the assurance of the extended warranty.  Check to see if there is anyone who will service Danby products in your area before you buy.
