Product review (5 stars): Sounds like people either love them or hate them. I love them.
Pros:

-- So quiet you don't hear it even if you're in the same room. Having a Bosch is like getting another room in your house.
-- Cleaning is amazing if you use the right detergent for your water and your water isn't too hard. Finish Tabs work extremely well for us.
-- Efficiency is phenomenal. Uses extremely little water and electricity so over the life of the dishwasher it will save you a few bucks.

Cons:

-- You have to use good quality detergent. If your detergent is poor quality I think the problems are magnified in the Bosch because it uses so little water.
-- Racks are odd and take some getting used to. They have good features but I like American style racks better.
-- There is no dry cycle. So dishes (especially plastics) can be a little wet when you take them out. That, along with 2 hour cycles is the price you pay for ultra energy efficiency (the dishwasher only uses about $20 worth of electricity in a YEAR).

Everyone should know: If you want ultra-quiet, the price you pay will be long cycles because the dishwasher is running at lower water pressure. The faster the dishwasher, the louder it is going to be. So I suppose speed versus noise is the tradeoff you should be aware of when you buy the dishwasher. If you want quiet Bosch is a great choice. Though there are other good choices as well.
