Was easy to install, easy to get the app and to connect the app to the unit was also extremely easy. It cools very quickly in our space of 460 sq ft. The app is also truly easy to use and control where ever you are in the house or away from the house. I just really love having control of my A/C unit on a app on my cell. It is so convenient in every which way and it saves you money. You will never be too hot or way to cold. The best part is if your in bed sleeping or just laying there and you are too cold or too hot. You can pull up the app, change the temp. without having to get up out of your bed to do so!! I just really love it!!!
