Our kitchen (and house) is super small so hanging a quiet dishwasher is a must since it's all one big room. I've been running this once a day since we installed it and it works great plus it's so quiet. I can't even tell if it's on if it weren't for the light. 
I also have been using the remote start with the app which I didn't think I'd use but have been using it almost every time.  
The 18" size has been fine for our house of 3.
