Product review (5 stars): Very pleased with the performance
This thing is actually quieter than the built-in (Whirlpool, so not a bargain brand) dishwasher we had at our old house.  Maneuvering all the plates in can be a bit of a challenge with the narrower width, but that's the trade-off for portability.  We were planning to only use this until we redo our cabinets, but are seriously considering pulling off the shell and mounting it permanently instead of going to a full-size washer.  Very pleased with the performance.  As others have noted, it doesn't have a dry cycle, but cracking the door after the load completes works out just fine.  Takes right at two hours to do the all-in-one cycle (for using the Dishwasher tabs) and we've had zero issues with our stuff coming clean.
