I couldn't be any more pleased with the ease of operation of this machine. It was realy value priced for the performance it gives. Cleans all my normal dishes perfectly and no technical knowledge needed to operate. No computer classes needed to figure out how to run it as with all the other machines I looked at and at a much lower cost than the more technologicly advanced ones with lit up buttons and so many functions to figure out . Im old school I guess and this is the machine for us old schoolers that like a well built machine that simply does the job and a great value for the pocket book.
