Product review (5 stars): I love it - But
I love it - But:  I've been installing DWs in my wife's rehabs for 15 years, and this kit looked like it would do the job - and it would have for probably any other DW than a Bosch Ascenta!

Usually, the elbow screws into the DW inlet with a little Teflon tape on it, and then the flex line is attached on both ends.

Not so with a Bosch Ascenta!  Instead of the DW inlet being female, it's male - so this kit won't work.  I couldn't find what I needed on AZ so I had to go to Lowes and they had a kit that supplied parts for so many connection options that I now have brand new fittings that I'll never use.
