Product review (2 stars): This. uses. so. much. water.
1. This uses SO MUCH WATER if you use it according to the instructions. The faucet is running the entire cycle, about 75 minutes. The average sink faucet uses one gallon every two minutes. My research indicated that if the dishwasher was not taking in water, the pressure would cause very little water to actually come out of the faucet, so it's like it's running but not running. Well, I'm using the adapter and hose that came with the machine, and there is a *lot* of water that gets wasted. It's not a very good seal, if it's even possible for the faucet to run-but-not-run in the first place. I plugged my drain to see how much water was being used, and not even halfway through the cycle (prewash, prewash, wash, rinse, rinse -- this would have been halfway through wash) my sink filled up all the way twice. I couldn't bring myself to continue with the water running nonstop. This is the only way you can actually run this efficiently:
>>>Start with the water on. You can hear and feel the water going through the hose. The dishwasher isn't really doing anything.
>>>The dishwasher will start making the churning dishwashery noise. At that point you can turn the water off. If the dishwasher  needs water and there is no water supply it will automatically pause. You are not putting the washer or cleanliness at risk.
>>>After it does it's thing it will make no noise for a few seconds
>>>The water will dump out
>>>No noise again -- turn water on, then after a few seconds you can hear/feel the intake
>>>It will go back to the churny noise and you can turn it off again
>>>Repeat, repeat, repeat -- cycle is prewash, prewash, wash, rinse, rise.
*** If you are away when it needs water, it will pause, and after a while it will beep loudly until the water is one. Helps cut down the babysitting a little.

2. If you do not have a standard faucet, I would strongly recommend not buying a portable dishwasher at all, be it this model or any model. You must use the aerator/adapter that comes with the machine. If you can easily unscrew your sink's aerator without having to take anything apart to access it, it will probably work. If you have a sink/sprayer combo (a "fancy faucet"), be warned. There are youtube videos that say it's easy, that you just need an adapter -- but, they all have different sizes and threading, and it may not work at all, and you'll be stuck with a $250 dishwasher on your hands that's a pain the rear to ship back. My husband ended up installing a new faucet after we failed to find an adapter that would work. Not everyone has such a handy person in their family or a landlord that doesn't mind.
