We have installed the dishwasher in our IKEA kitchen under the sink, so that the door still to go. This works without any problems and the dishwasher will disappear behind the door.
I find the TSG707 looks with its LED display and buttons of a lot better than its predecessor (?) TSG705. In addition, you can see it the minute how long the program is still running.
There are of course different wash programs. We tried so far have 2 programs with powder dishwasher detergent from Aldi Süd. The result in default (total 120 minutes) and Express program (60min) was always clean without hesitation. Coffee / tea-cups, plates from the barbecue, cutlery, etc .. One must, however on the watch of the arm, under the basket, can move freely.
I think the unit completes its service in our closet (with closed cabinet door) very quiet.
For the 2-person household, I would recommend this device without restriction.
