After a lot of research I went for this machine. Here are the pros and cons:
all alarm beep noises can be fully turned off if desired (most other brands fail to offer this option).
decent washing performance.
upper tray layout ideal if you use a lot of plastic containers
very easy to use intuitive control panel (easier than some other brands I have used recently).
air dry feature ensures perfect drying if you can let it air at least a few hours before you start unloading.
while no louder than most other machines, its still a bit louder than expected, with no insulation blanket fitted to our unit
the lower satelite spray arm makes a slightly annoying low rumbling noise (we fixed this by buying a compatible non-satelite-type spray arm).
the machine makes a startling bang noise when opening the door at the end of a program (caused by detergent dispenser cap hitting door frame on opening)
lower tray layout inferior to our old AEG, not as many options for fitting our dinner plates while leaving enough room for all our pots.
the upper tray is a bit wobbly and has trouble lining up with sprayer pipe at back if loaded too much at the back, so you need to be careful.
Overall despite some flaws, I would recommend this machine, as all the alternatives have their own flaws too.
