Product review (4 stars): Great little dishwasher, if it lasts - not for everyone, consider all your options and needs carefully
After much debate and almost going with a Kenmore 17" portable for my small apartment (which would have cost nearly $600.00 new with shipping), I decided on this.  It was the least expensive portable dishwasher I could find - paid $215.00 here on Amazon.

***Important  to consider in purchasing a portable dishwasher***

KITCHEN FAUCET ADAPTER - the adapters that come with these portable washers (dish and laundry) are meant to easily connect to a standard kitchen faucet only.  Some of the designer faucets will not accommodate these adapters without modification, if at all.  You can buy adapters fairly cheap from hardware stores, so you may want to buy one of these first just to make sure it will work with your sink - thereby not blowing a bunch of money and/or necessitating the unpleasant chore of re-boxing the product and returning and paying a restocking fee.

COUNTERTOP VS LARGER FLOOR MODEL - keep in mind that the countertop will consume a great deal of valuable counter space.  It is almost better for a larger kitchen ironically for this very reason.  The counter space on either side of my sink was not sufficient for this dishwasher to fit.  My solution was (thanks to another customer review) to purchase this utility cart for $89.95:

This seemed a better option for me because I'm single and didn't really need a larger portable dishwasher, and plus the bottom shelves of the utility cart can be used for storage.

The flip side is this dishwasher will only hold so much at one time.  It will accommodate even my largest stock pot, but that won't leave room for too much else.  So for more than 2 people and/or for someone who cooks all the time and generates alot of dishes every day, this will not be adequate unless you want to run multiple loads with it.

If you can accommodate or prefer a larger portable dishwasher, I recommend checking on Craigslist especially if you live in a city.  You can sometimes find great buys on good quality appliances.  But as the larger washers are very heavy you will need the right vehicle and help to get into your home, and there is the risk of buying from a stranger a product with no warranty.

DANBY DISHWASHER ITSELF:

It arrived by UPS extremely well packaged from this supplier on Amazon - absolutely could not have been better.  The dishwasher box was in a larger Danby box with styrofoam sheets around it, and then the Danby box also had plenty of cushion.  This contrasts with an other larger floor portable dishwasher item I purchased some time ago from Walmart that arrived damaged and non-working and thus had to be returned.

Assembly was very easy and intuitive, but I found the product manual online first to read up on it.  Absolutely one of the best and most thorough product manuals I've ever read especially for these smaller, cheaper appliances.

Modifications I had to make:
The grids over the silverware basket did not allow my larger-handled silverware to fit.  I was pleased to see they were removable and then I just loaded my silverware normally.

Dishwasher operation and performance:

The unit operates unbelievably quietly, so quiet in fact that I took advantage of the pause feature periodically on the first run to make sure it was doing anything.

I had a stock pot (10 in deep x 8 in diameter) that I really didn't expect to fit but it did.  It had food dried on the bottom that could not easily be scrubbed off even by hand without alot of soaking.  I was astounded that when I pulled it out it was absolutely spotless, if anything cleaner than it would have been in some built-in dishwashers. Everything I have washed in it, from plates to skillets to silverware has come out very clean.  My water is of less hardness than some places but not exactly soft.

***PROBLEMS SO FAR***

FAUCET ADAPTER LEAKS - as the manual disclosed, the faucet adapter did leak when I snapped on the unicoupler and turned on the faucet.  I wrapped the threads of the adapter with plumber's (teflon) tape, and initially the leaks stop but it started again.  My taping job was not the best, and I've ordered a new product I found. If this stops it I will edit this review accordingly, but so far this is the only real problem I've had.

PLASTIC DISHES DIFFICULT TO HOLD IN PLACE - Think of this dishwasher as the bottom half of a large built-in dishwasher and what happens if you put lighter items in the bottom.  The spray arm is so powerful that some lightweight plastic dishes will get blasted out of place by it.  Items small enough to fall through the grid will then block the spray arm from turning.  I put my gladware up on the cup shelf which helped some.

As others have noted, thicker stoneware dishes do not work well in this.  Standard Corelle dinner plates will fit fine, but I cannot fit 6 matching salad bowls in as the loading diagram would indicate.

Larger silverware, spatulas, etc are too tall for standing in the silverware basket.  I simply laid mine atop the cup shelf and they came out fine.

DURABILITY OVER TIME?

I did take note of comments by people who have had to purchase several of these over the years because they wear out relatively quickly vs the larger, more expensive brand-name portables.  Then again, I read reviews that indicated the quality of those models is not what it used to be either.  I will come back to report if/when this thing wears out or starts giving me trouble.

Initial satisfaction - good.
