I bought this fan approximately four years ago to keep my room cool during the summer. I expected a short life span but have been more surprised that it keeps going every passing year. the fan runs almost non stop for the ENTIRE summer and a large portion of spring winter and fall for air circulation. I have run the fan almost exclusively on the lowest speed, of three, for all this time with the osolation on. everything still works just like new, even the switch which has seen extremely heavy use, on and off hundreds upon hundred s of times, works just as perfect as the day it was new. the only proablem mine has ever had was a very slight rattel whenever turned up to the second or third speed. the fan is quiet on the first speed, and easy to fall asleep with. though it does get lowd on 2 and 3, but moves substantially more air. now, even though I love this fan, it isn't going to blow you away, if ya get what I mean, but you will quickly realize that low is sufficient for most cooling needs and medium or high works fine for mid day when it is the hottest, and I live in utah in a room with huge south, and partial east west facing windows, and in the summer it has hit 80 with the home ac on, so it has a good cooling effect. the osolation feature turns the fan just shy on 90 degrees, so the fan is best suited for a place in the corner. overall I am extremely happy with this product and am NOT PAID by anyone to leave a positive review, I am just surprised with the price of this how long it has lasted, with NO REPAIRS, how well it works, and its price point. overall it is a great value. p.s. you can tell from the disgusting dust build up it has seena lot, and has been cleaned multiple time, the dust doesn't come off easy!
