Product review (5 stars): Awesome, no more dishes by hand!
It does what a dishwasher is supposed to do - wash the dishes.

In case you've never owned a portable dishwasher before, it goes like this - you hook it up to the sink with a tube that pumps water to the dishwasher and then pumps dirty water back into the sink. Mine came with a special part you hook up to the faucet. You plug it in, load it up, add some soap and let it run. There's slightly more steps than a normal under-counter dishwasher, but it's smaller and thus there's more room.

However, it's worth noting that this thing is bigger than a microwave. If you're going to put it on a cart, a microwave cart probably won't be big enough.

I've only used the 'rapid' cycle, as other people seem to recommend, and it's worked great. There's no leaking and no mess - except if you're careless about disconnecting the sink hookup, but that's to be expected. It's like when you turn off a garden hose and lift it from the middle, water still in the hose is bound to come out the only way gravity will let it.

It doesn't seem to have any kind of sound muffling so it's a bit loud. Not too loud to run in the middle of the night with neighbors sleeping one room over but it's no gentle hum either. It's heavy too, I nearly hurt myself getting out of the (huge) box it came in. Neither of these are enough to overshadow the performance and general convenience though.

I've read a lot of bad reviews about this thing. I've come to the conclusion that the majority of them come from people who have never used a portable dishwasher before. Having owned a larger model myself, I knew the basics of what to expect. As with any plumbing that comes partially 'pre-assembled' you need to tighten and adjust everything to avoid leaks - machines put these things together most of the time, not people. You check the seals, the general quality of the product and watch over it the first time you run it. Just in case. If something goes wrong the odds are that it was used improperly.

All in all, I'm satisfied. It works well and I don't have to do the dishes by hand anymore.

I still stand by everything in my review. This thing is a great convenience. I haven't had any leaks, malfunctions or trouble.

A year later and still working like a dream. If it starts to smell inside, just run a cycle with a little bleach and it'll take care of that. If some build up starts to happen around the seal, just wipe it down with a sponge. Both of these things can happen with any dishwasher, so it's not a big deal.

Minor (stupid) user-end issue today. A chopstick was poking into the seal when I closed the door. It still locked closed and I didn't notice the chopstick sticking into the seal until one of the rinse cycles started. A lot of water leaked out. I caught it almost right away and it took about 20 minutes to clean up. There was no damage to property or the dishwasher though. Still totally recommend it.
