This turned out to be an excellent purchase so far (reliability to be determined.). I am getting too old to install/take down large A/C units due to their heft and this appears to solve the problem. Once installed it can be left on the window year round and best of all the window can still be used. The space I am cooling is at the rated limit of this unit however it seems to be doing a great job cooling it. The app is great letting you control the A/C remotely and monitoring power consumption. It's very quiet and certainly stylish.
