Bought this awhile ago , maybe amonth or two, its been working well! it definitly cools the imidiaate 10 ft radius around it but definitly strugles with the rest of the room, but is no problem since i spend my time quite near it anyway. I would say its louder then some portable AC Units ive seen, i dont mind the white noise however. The instalation was quite easy, used a handsaw to measure down the window panel. Would recomend for price to                useibility tbh.
