Product review (4 stars): I don't exactly own one of these...
DISCLOSURE: I do not own one of these. I do, however, own the model it is replacing, the DDW1899WP (here: https://www.amazon.com/Danby-DDW1899WP-1-Portable-Dishwasher/dp/B00FFZEU6A/ref=cm_cr-mr-title). The specs are identical, but I will note in some points things that I don't know would apply to this replacement model.

WARNING!!! Beware the one-star reviews posted (as of this date) for this product. One is a review of a different product, and the other one is from a TROLL - read my comment to his "review" and you'll see that he is obviously lying (could not possibly have bought one of these as he claims, and is posting the same one-star review against multiple Danby products). One of Danby's competitors, or a seller of products from Danby's competitors? You tell me.

ORIGINAL REVIEW

First, make sure you shop around. I got mine from the website of that big chain that starts with W and ends in Mart, $100 less than the best price I could find on Amazon and free shipping to the store. Wow. EDIT: as of this moment I see prices for this on Amazon range from $891 (gulp!) to >>$85<< - but that $85 doesn't include the additional $350 shipping. And this item has several different listings on Amazon. So like I said: shop around!

COMMENT: Yes, that continues to be true for this new model: I see one listing on Amazon, for $612 (Prime) and a different listing for $542 (not Prime).

1. Absolutely true that it is very quiet. The review that you have to be standing right next to it in order to hear it is, in my opinion, a bit of hyperbole, but subjectively about a third the noise created by my old Kenmore (Whirlpool in disguise).

2. Also true that it does not completely dry dishes. Once the unit beeps (more on that in a moment) to tell you it's done, crack the door open so the steam can escape.

3. And yes, it's true that it takes forever to complete a cycle. But here's the thing: it uses very little water (again, about a third as much as the Kenmore) and incidentally, about a third as much detergent; obviously, they have traded water volume for cycle time. Does it really matter that a dishwasher takes longer? I guess if you really needed a full-size dishwasher but couldn't make room for it so you need to turn around several cycles back-to-back in order to wash all of your dishes, that could be a consideration. But if all you really needed in the first place was an 18", who cares if it takes two hours instead of one hour, especially if it is using less water, less detergent, and (according to the Energy Star rating) less electricity?

4. Eight place settings? Of what, dollhouse dishes? Now that one *IS* hyperbole. The owner's manual shows a picture of the rack filled to the gills, plates and bowls facing down. Yes, it is possible to fill the rack from one side to the other with plates and bowls...and quite impossible to then slide the rack into the dishwasher and close the door. If you go by the owner's manual, then the tines by the left side of the rack are there only for show: you cannot actually put anything there or they will overhang the side of the rack. Oddly, one of the pictures in one of the several Amazon product pages for this unit shows the rack filled with bowls and plates facing UP, in which case you can in fact fill the rack...but that contradicts the owner's manual! (I tried washing dishes with the plates facing up and it does in fact work, so is the manual wrong?)

The upshot is that this is a four-place setting washer and a bit tight even for that. This unit is fine for two people washing dishes every several days, or a family of four washing daily, but that's it. They have compensated to some extent by very carefully engineering the small interior - the smallest interior of a standing dishwasher I have ever seen, probably to make room for the extra insulation that makes it so quiet and energy efficient - to maximize what you can get in, but the special bowl holders and flip-down mug rack aren't going to help when you have a giant salad bowl or anything else unusual in size to wash. The good news is that because the top rack has its own independent spray arm - a standard feature in 24" washers but fairly uncommon in a compact portable (neither of my Kenmores had one) - you can get away with piling one or two large items on top of other dishes in the top rack; presuming they're flat enough to still slide the rack back in, they'll come out clean. EDIT: thanks to "MartyytraM" for pointing out that the the entire upper rack assembly, including the spray arm, can be moved up or down. Unclip the white knobs at the front of the rack arms that extend out when you pull the rack out, pull the entire rack assembly out of the dishwasher, and re-insert it using the second (previously unused) set of wheels on the rack and re-clip the clips. That gains you 6cm more room up top, but it then just barely clears my large plates downstairs. UPDATE: Two weeks of using the dishwasher with the upper rack set to the lower position and very pleased; no contact with the large plates downstairs. One unexpected bit of information is that large plates CAN interfere, not with the spray arm but with the roller wheels on either side of the top rack: if a big plate is all the way to the left of the bottom rack, it'll whack into the wheels of the rack above when you try to slide the bottom rack back in. Solution: put your biggest plates in the center of the rack and the small stuff over on the left.

COMMENT: I have no idea whether this new model has an adjustable top shelf; can any owners respond? The previous model had the capability as noted, but it was virtually impossible to know that unless it was specifically pointed out.

Speaking of the owner's manual, it fails to provide some useful bits of information. I had the devil of a time trying to figure out how to wash wine glasses; I use the excellent Quirky Tethers (do a search) and was frustrated by the fact that the bottom rack has large areas with no supporting wire running underneath (so on one side of the tines a wine glass has something to sit on, but on the other side they'd just fall through). It turns out that there is a dedicated place for wine glasses: the left side of the top rack (the aforementioned mug rack) also doubles as a wine glass stem holder, with special inserts to fit the stems into, holding the glass at a downwards angle (doing so means you can't fit any mugs underneath, but you can put mugs on the right side of the top rack). You can fit four regular wine glasses or three jumbo Riedels. That's great, but there is zero mention of this in the owner's manual; I figured it out by accident while Googling "dishwasher wine rack" and saw a photo of this exact same solution...on the website of one of Danby's competitors!

5. It does a GREAT job of washing dishes. I tried a "regular" wash cycle with maximum detergent (hint: don't fill the entire detergent dispenser, you fill either the left side for small loads or the right side for big loads, not both) and dishes and utensils with caked-on food and everything came out sparkling. I haven't tried non-soaked, baked-on food yet but there is a pots-n-pans cycle for that. The very long soak pre-wash may be to credit for this. I was highly skeptical of the unusual silverware basket, in which forks and spoons go in handle-down: with most of the water pressure wasted on the handle and the plastic holder itself, how can it do a good job of cleaning the business end of the silverware? But it does. EDIT: it just occurred to me why this works: the top rack spray arm. While the water going UP has to fight its way past the basket and the handles, there is twice as much water coming down from above than most 18" dishwashers, and half of that is falling from a greater height. Smart.

Here's another helpful tip not covered in the manual: if silverware has to go in the special basket that holds each fork and spoon facing up, then where on Earth do you put utensils? In turns out that the special silverware basket is actually two trays side-by-side, the tops of which can be unclipped and removed to reveal a conventional dishwasher silverware basket underneath. I removed one top, put my utensils on that side, and continued to put ordinary silverware on the side with the special holder top. Big utensils like spatulas you'll have to lay down in the top rack, but that's true of all but the biggest of dishwashers anyway.

COMMENT: I assume that this new model uses the same or similar silverware tray.

6. I use my portables as a sort-of built-in: I slide it under a counter and hook it up to the hot water and drain under the sink. This is one big star off as I discovered to my horror that the water feed hose is connected directly to the solenoid valve at the bottom of the unit (held on by a oetiker clamp, non-removable). This is unlike any dishwasher I have ever seen and means that you cannot simply remove the portable hose and screw on a replacement or an extension (and the portable hose is short, about 1 meter). It also means that if that hose ever leaks, you're screwed. In exchanges with other posters here on Amazon it appears that earlier versions *DID* have a screw-off hose and that is a huge move down in flexibility and long-term reliability. How much does a washing machine hose fitting cost, wholesale? Fifty cents? Shame on you, Danby. Anyway, I sliced the permanently-attached hoses in half with a carpet knife (voiding the warranty, no doubt, while a screw-on hose would mean I could just put the old hose back on if needed) and, with great trepidation, connected it to the push-on compression line I had coming off my hot water line with an adapter and barb fitting from Home Depot, secured by a radiator hose clamp. Not a drop of leakage, which leads me to...

COMMENT: I am hoping that the one thing that Danby DID change is that they admitted their stupid mistake and have gone back to a screw-on fitting. Could an owner (who is strong enough to flip the machine over on its top) please comment? That would make it a five star product.

7. ...Superior solenoid design. My old dishwasher, and its predecessor, and every washing machine I have ever owned, had plunger-type solenoid valves: one moment it's on, the next moment it's off. You know what I'm talking about: the dishwasher or washing machine makes a huge CLUNK sound as the water comes on or off. That creates a momentary spike in the pressure inside the hose and can cause anything short of a perfect seal to leak and eventually fail. The Danby valve opens and closes more slowly, preventing that sudden thump. Hence, no leaks at my jury-rigged hose connection.

8. It would not fit under the counter on its wheels. It is not obvious how to remove the wheels; what you do is push a large flat screwdriver in perpendicularly at the top and push off the slip rings that hold them in place. Removing the wheels creates a new problem: the Danby cannot sit on the floor without wheels, because it has an irregular bottom. But inboard of the wheels there is another set of holes, I'm guessing put there for the undercabinet version so both models can share the same chassis. It turns out that a set of flat office chair feet fit perfectly; I used these: <http://www.amazon.com/gp/product/B00CF06M1O/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1>. They'll wobble a bit when the dishwasher is flipped over, but once you set the dishwasher down they're rock solid. They'll need a nudge to get them to go into the holes, one tap of a mallet or a hammer will do.

COMMENT: No direct knowledge of how this new model is made, but since the chassis is obviously shared between models it is likely it still accepts office chair feet.

9. Water is not heated during pre-rinse; but it is heated during main wash cycle. I verified this by running it off just cold water and checking the temperature at various points during the wash. The pre-rinse stayed ice cold but the wash water warmed up over time until it was steaming hot. Not hot right at the start so it does not pre-heat like some dishwashers, but with such long cycles that shouldn't make a difference.

10. The many pages of instructions about adding salt and securing the salt dispenser and monitoring the salt indicator light is, for almost everybody, meaningless. It's nice that the unit has a built-in salt dispenser but that's only needed by, and that portion of the manual only has to be read by, people who a) have very hard water and b) don't already have a water softener. If like most people the water coming out of your tap is reasonably soft (if you're not sure if it is, then it is - you'd know) then ignore the instructions as well as the idiot light on the front panel.

11. It beeps. It beeps when you start it, it beeps every minute when the door is open to remind you to close it and start the cycle, and it beeps a bunch of times when it's finished. And no, you can't turn the beep off. Grr. At least it's not a particularly loud beep.

In conclusion, some compromises (and some extra-frustratingly the result of rather short-sighted decisions by Danby that are really unnecessary), but does a very good job of washing dishes, is very quiet, and - if you shop around - is an outstanding bargain.

COMMENT: Take that one with a grain of salt (pun intended). If they have in fact gone back to the screw-on hose connector (or improved the manual, or given the option to turn off the beep) then it is simply a five-star product, period.
