We like the third / top row for the bits and bobs that need to be cleaned too! knives sit in there upright and unable to create a hazaard. lids to water bottles etc.
overall - with kids loading it - it has stood up well, and gets the dishes mostly clean - the odd dish needs to be rewashed, but that is likely more to do with kids not rinsing/removing large food particles before loading.
Interface for delay is not the best. If you accidentally touch it you have to update 24 hours to get back to non-delay start. Also ensure you have some clearance at the top or you can't cancel once started without access to the top touch buttons. Cleans dishes well and is quiet.
