Very good ac unit overall, powerful and quiet (although I’ve experienced quieter ones from some other brands). Another issue, pretty important in my opinion, are the mounting hardware provided to install the side curtains, they’re not ideal and I actually had to salvage hw from another brand and modify those to attach the curtains at the bottom! Also the brackets to attach the unit to the sill is way above the sill, the provided hw would never reach the sill, instead why not just have a hole in the middle of the top rail to attach to the window through a screw? In my case I just didn’t attach the brackets, not ideal but oh well! Otherwise pretty good, 4/5.
