Replaced an existing Bosch DW that I thought should last longer than it did (only 10 years) and expected a similar installation to what the old one was but was surprised when the layout was 100% different.  Difficult to install and did not like the fact that the plumbing and electrical needed to be routed through the cabinet next  to it.  Great working and very quiet.  Much quieter than the old one.  Just thought the installation was a lousy design.
