Bought all Bosch appliances with our new build last summer for the quality.  The microwave functions fine, but I have 2 big complaints.  
1) The door should have a side hinge option - it's too hard to get foods in and out above the stove witht he door opening the way it does.  It really is a safety issue.  
2) The dimming issue drives me nuts.  Doesn't matter if you set it to bright, it dims within 30 minutes later. Have had the control panel replaced - made no difference.  Was told it's supposed to go to sleep and then wake up when you open the door or press a button - wrong - that doesn't work.  The above issues are even more of a problem for my elderly mother-in-law who lives with us.  Would not have bought this model had I known what I know now.
