It sound like roars, it is good for using in hot summer days, still it doesnt fits for moisture areas, i think coolers are not meeant for this place, well good in air distribution but not good in use as because it has lots of sound and it is not a good thing to use in home as I got some electric shocks while touching the switch might they have some faults, i have some more disdvantages about it is that its water gets fastly empty and also it needs more elecetric volts hence not suitable for home those have low power energy.
therefor as a buyer I advice to go for this product only if you are suitable in my review.
