Just got this washer this morning and I've been using it all day, I purchased the 300 series because of the price point. It has all the performance of the 500 and 800 series', and I really don't need the extra features of those models. I was surprised by how quiet and smooth the washer is, especially considering it's 1400 RPM spin speed. I liked the simplicity of the controls: turn one dial, touch one button, and the washer does the rest. The cleaning performance has been first rate.  I did a lot of pre-purchase research, and Bosch is at the top in reliability, so I look foreward to a long and happy relationship.
