Product review (5 stars): Dishwashing is now fun and fast and they get really really clean. Very pleased.
I am very pleased with this dishwasher. Did a lot of research on all brands of portable dishwashers before purchase including Consumer Reports (that doesn't cover this model) and user reviews. I have been using it daily for two months.

Pros:

It is very quiet. Makes a gentle, soft, comforting sound.

Washing dishes used to be a tedious bore, soaking hands in hot water and toxic detergents. Now it is fun to do and fast, dishes get much cleaner this way too.

Glassware comes out sparkly and gleaming.

It has as small a footprint as any model but it holds a lot of big things.

The top basket cleans very well due to a clever system of feeding water to an upper sprinkler.

It has a limited digital read out panel, only the remaining time. But that is all I need to know, not all dishwashers show it. I recall it also shows diagnostic error codes, but I have never gotten any. The dishwasher also beeps to indicate some things, like powering off.

It has a stainless steel liner:

"A stainless steel dishwasher tub resists corrosion and is more durable than plastic. Stainless steel can withstand more heat than plastic, meaning the water can be heated to a higher temperature. It also retains heat better, increasing the efficiency of the drying cycle and saving the homeowner money."  It is also insulates sound much better, for quiet operation.

It has a lot of cycle choices. The buttons are easy to figure out and use, LEDs show the selection.

The door is very easy to open and close but seals well.

Very easy to hook up to the faucet, no leaking.

Dries well without having a heat dry cycle that uses electricity.

I have fairly soft water, don't use a rinse aid (what? Spray a possibly toxic manufactured chemical all over the dishes as the final step?), yet rarely get spots, using the cheapest generic dishwashing powder.

The top is convenient counter space.

Very easy to clean.

I rinse the dishes of visible food particles so I only have the clean the filters every few months. Very easy to remove and clean.

Gets the water pretty hot, going by the steaming plates when I open the door. My tap water is not particularly hot.

Don't have to soak my hands in detergent washing by hand. Saves a lot of time even with rinsing (which is not necessary unless the food particles have dried hard.)

Very flexible baskets with tines that can be lowered, to allow easy stacking of all kinds of dishes.

I can put large pots that cover the bottom sprayer and the top basket still gets clean.

I have washed wood and plastic items in the lower basket, no problems.

Tips:

Unpacking I just sliced open the several layers of cardboard so the top and sides fell away on all sides. Then I bundled the many large pieces together for disposal. A lot of trash.

With fairly soft water, I don't need rinse aid. However natural, cheap and safe rinse aids are described on the internet.

Expensive detergent doesn't make a difference for me. Cheap generic is fine.

I purchased a few "baby item" baskets to use for things like small bottle tops, chopsticks, and other items too small to stack in the baskets. These two work fine for various size items:

When I open the door, some dishes are still slightly damp and a very few with strange shapes have a few drops of water. They are hot so dry quickly in the air after I pull out the two baskets.

If a dish has something dry and hard, like dried oatmeal, it won't get removed. I soak those in water for a while first, very quick and easy. This is likely true for all dishwashers, since they don't work by forceful jets of water but by long cycles of very gentle, dissolving sprays with corrosive detergent.

I took the top off half the flatware basket to hold items with handles too big for the slots. This also works for spatulas, serving spoons, etc.

I always use the long cycle with the extra rinse.  May work fine on shorter cycles but I like making sure to get rid of all the toxic detergent.

I was able to drape a few shirts over the baskets and wash them using very small amount of clothes detergent. I turned on the cold water and used the rinse cycle to avoid any hot water. I have to repeat the rinse cycle once or twice to rinse, and hang dry the items. Convenient way to wash a few items right away.

Points of concern:

At first a small pool of rinse water remained in the bottom of the dishwasher. This is normal for many brands. Some of it gets ejected at the start of the next load. Yet leaving a small pool of water in it for any length of time does not seem hygienic. Over time the amount got less and I just checked, no water from the last load.

When it arrived, well packed, the box was intact. Yet when I opened it up the top of the dishwasher was covered in wet, coarse gravel. Very strange but the dishwasher was clearly brand new and undamaged. A mystery I have seen reported in other places.

One exterior sheet metal screw was missing, does not cause any problems.

All dishwashers seem to have high failure rates, some brands much more than others. Yet research showed insurance was not worth it. Nor is warranty repair if the customer has to pay shipping. Some companies use local home-visit repair people, but it can also be hard to get a company to honor their warranty (for example a very short list of approved vendors). I don't believe this brand has great warranty service, but I took a chance that if it lasted 30 days I would be good for a while. Kept the packing materials (cut up and bundled to save space) just in case I needed to take advantage of Amazon's generous return policy. I have been using the dishwasher daily for two months with no problems.

If you live in a very humid climate, the lack of a heated drying cycle might possibly be a problem. I would never use it.

Conclusion:

The only better way to do dishes is to eat out. If you don't have a dishwasher, don't have a lot of extra space in your kitchen, and don't want to pay $500 to have dishwasher permanently installed (taking up storage space), I recommend getting a portable one like this.

Post Script:

Research on the internet. All plastics leak toxic chemicals into food, BPA free may be even worse (see Mother Jones on this). Almost all glazed ceramics leak heavy metals (look up third party research on this). A very few brands of ceramics use lead free glazes (e.g. Fiesta, Certified International). I mostly use Corelle dishware (it's made of glass but very light and durable using a special construction method), borosilicate glassware (durable, crystal-like shine, most resistant to thermal shock, from freezer to microwave.) or stainless steel.
