This being our first non window unit - we are pretty impressed. We liked that it came with its own size customizable window piece where the exhaust hose fits. It went in our old window sill and attached in less then a minute. 
Wifi Set up was easy, the app installed and worked for long distance on/off and temperature settings as well as you also have the internal temp of your room displayed. Runs super quiet by everyone's standards, much quieter than even the window unit. The size of the unit is unobtrusive, about like a dorm fridge. We have a four room combo and it cools the room it sits in the best, then just a few temperature rise for each room as you get further away from the main room. Filter cleaning has an app notification when it needs cleaning, and is easy to rinse with a sink/shower sprayer, dry and put back in place easily. 
Overall a great product!
