We  are on a limited budget & needed a small size kitchen fan. We hoped this fan would work better than the old one that needed replacement. The high & medium buttons are the same fan speed, & the low is barely discernibly different. All three speeds are extremely noisy, & the fan doesn't do much better to reduce cooking smells than the old one did. We honestly have to shout to hear each other in the kitchen when the fan is on. Very disappointed. Would not recommend.
