Great things about this fan-very powerful, even on lowest setting moves a lot of air. I use another window fan to bring cool air in (when it's cooler outside, of course) then use this Newair fan to move the hot air out. When weather conditions are right, this cools down the space very quickly. I feel confident the fan will last (this is summer #2), and the grill comes off for cleaning. The only negative-and this is mitigated by putting a nonslip mat underneath-is that because it is so powerful, the fan "skates" around on the hardwood floor, but, easilty addressed. The good performance of this fan led me to purchase a portable ac unit from this company this year (will do a separate review for that). One mention, a hd fan like this makes some noise-does not bother me, but is to be expected.
