I purchased my Frigidaire dishwasher to replace a 25 year old Hotpoint dishwasher.  After weeks and weeks of searching and reading many reviews, I can say I am very happy with my purchase.  My dishes are coming out very clean.  I did go ahead and purchase a rinse agent which helps a lot with the drying process because we like to use the quick wash which does not have a very long heated dry cycle.  I was reluctant to use a rinse agent because I like to use a natural dishwashing detergent.  I did find 7th Generation rinse agent which I like very much.  Overall, I am very pleased with my new dishwasher and would recommend it to anyone.
