Love this AC unit. It far exceeded my expectations on multiple levels. First the design is sleek and has a low profile. Because of the horseshoe shape, you are easily able to slide it’s over the window sill. If the window still is too wide, no worries, you can adjust the opening of where the unit rests on top of the still. The functionality provides 4 different modes; cool, can, Eco, and dry. It also has 4 different speed settings; auto, quiet, medium, and high. Even on the high mode is very quite. The noise from the unit doesn’t overpower the room. I installed it in a larger room and had no issues cooling the room down pretty quickly. It comes with a remote but best of all there is an app that can be downloaded to operate it remotely. Over all, fantastic unit. Highly recommend if you need a portable unit to cool down a room. Great to have in case of an emergency if your central AC unit goes out.
