Product review (4 stars): Danby Does Pretty Good
I acquired my Danby dishwasher about a month ago as a replacement for my previous portable dishwasher, an Equator 20" PLS602 model.  While I am quite happy with my new machine, there are many things about the old one which I miss.  This review will be a compare and contrast of the two models.

My old Equator was a 20 inch cube (20x20x20) which, though still small, provided enough space to put in large plates and frying pans. The interior of the Danby is just as wide and just as deep as the Equator, but it is at least 2 inches SHORTER than the Equator and I now find myself cramming in dishes which used to fit just fine and having to wash many of my frying pans in the sink (which, er, starts to defeat the purpose...).

The Danby has a stainless steel interior. This is a major bonus! My Equator had a plastic interior and though it held out for more than five years of regular use, eventually some of the plastic parts began to crack. I do not see this happening with the Danby.

The Equator has a plastic dial on the front which allows you to set the cycle and to view how far along the cleaning process the machine has gotten at any given moment. The Danby allows you to choose from five different cycles, but it's digital display does not tell you where in any given cycle it is (wash? Rinse? Etc.) Also, the very longest wash cycle on the Equator was approximately 45 minutes; the standard wash cycle on the Danby is nearly 2 hours!  It should not take two hours to clean 4 plates, 4 cups, and 4 settings of silverware.

The Danny has a viewing window -- this is kind of fun. The Equator did not.

The silverware caddy in the Danby is much too small, and I have taken the one from my Equator and am using it in the Danby instead.  Also, the interior rack of the Danby has such large gaps between its rungs that sometimes items actually fall through. This never happened with my Equator.

The Equator hooked up directly to a hot water source (in my case, from my outlet port on my hot water heater) and its exhaust tube had to be clamped onto a sink in order to drain properly. The Danby does not work this way: it's intake and outflow tubes connect directly to the hot water tap of your faucet through a snap-attachment. Mine did not come with the universal steel nipple attachment for the kitchen faucet, but this was only a minor inconvenience to get at the hardware store.

I acquired the Danby used.  Perhaps this explains its final quirk: at the end of its last rinse cycle on any of its five cycles, it does not drain. In order to make a drain I must turn the machine off, turn it back on again, and tell it to begin a new cycle. This will make the machine conduct a preparatory drain of the interior, and all I need do then is make sure it does not actually begin a new cycle. Easy enough, I suppose, but this is one more complication my Equator did not have.

And so I must give the Danby only 4 of 5 potential stars.  My biggest complaints are the small interior compared to my last model, and the incredibly long wash times.  But it does get dishes clean, yes, that it does.  If you are willing to wait long enough, and if you are willing to wash the big things by hand, the Danby will take care of the rest.

Oh, and it is noisy.  No debate on that.  I could never sleep in a room where this thing was going.

REVIEW UPDATE, 2/22/12:

I still have and use my Danby for almost all of my dishwashing needs, but some additional updates are in order.  First, about a month ago I discovered that the viewing window, which is made of acrylic, had started detaching from the door.  The window consists of two panels, an interior panel and an exterior one.  In order to re-seal the dishwasher, I had to disassemble the door panel, figure out why it was leaking, drill holes through the PVC exterior, and re-mount the acrylic interior window with stainless steel nuts and bolts (one in each corner).  This took me four or five hours, and a trip to the hardware store to get the screws.  I said before that the viewing window was kind of neat-- apparently it also makes the dishwasher vulnerable to leaks that, while not impossible to fix, are no walk in the park.

Second, about a week ago I thought the machine had broken since it wouldn't drain properly.  My repeated attempts to restart a new wash cycle only led to an "E2" error blinking on the display panel.  After much futzing around I discovered that the exhaust hose, made of vinyl, had become kinked in the back.  I used a steel pin, electrical tape, and a hose clamp to force it to un-kink, and it now appears to drain correctly.  Would have been nice if the exhaust hose had been rather more unkinkable.

FURTHER UPDATE: 2/13/2014

A few more thoughts/ experiences:
The swinging arm of the Danby is occasionally snagged by dishes or silverware that happen to poke down through the sliding dishrack.  Without the window, I would never be able to tell if this was happening or now.  I wish other kinds of dishwashers had such a window, but none seem to!  There is no "error" message to tell me that the swing arm is stuck, I just get a load of not-very-clean dishes at the end of the cycle if it snags on something.  The window is more than just neat, it's quite practical.

Another thing: the swing arm.  Despite the built-in stainless steel filter screen, some particles of food eventually do make their way into the swing arm where centrifugal force sends them out to the tips...  Where they become stuck, because the tiny holes at the end are designed for spouting water, not food bits.  In order to make the dishwasher function at its best, these holes have needed cleaning out every couple of months.  I take a propane torch and blast them clean (the food particles turn to ash, the steel is only slightly discolored, never damaged, and I don't heat up anything other than the tips of the arms because the central ring is plastic and would obviously melt if subjected to a propane torch flame).

Right now I am considering upgrading to an 18" Danby.  I have more dishes than this little item can handle.  But I am intending to give it to a dear friend as a gift: she has no dishwasher at all, and I think she will be very pleased with this one!  I know that *I* have been.
