Customer Reviews

Over 12,000 hours of dependable operation...
While checking Amazon in the course of recommending this fan to a friend, I was surprised by the mediocre rating people had given it and decided to add my experience to the reviews. Like Richard Shrum above, I'm confused about what fan some of the negative reviewers were talking about. A few of their comments don't seem to compute with the fan I own, which has 3720 marked on its frame, matches the picture above, and is listed on Lasco's website.

I've owned mine since April 2005 and have run it as a window fan (on low) from eight to eighteen hours a day, for about 325 days each year, and it still operates as well as it did on day one. With this kind of use, I've sort of expected something to go wrong or burn out, but nothing has. All I've had to do is turn it on, turn it off, and clean it every four or five months - a fifteen minute chore.

As I was writing this, I got to wondering just what my use actually amounted to. Based on very conservative estimates, I figure my fan has run about 3700 hours each year, or about 12,200 hours since I bought it. Impressive as that figure is, get this - since the fan runs at 635 RPM on the low setting, that means the fan's motor, bearing, and blade have revolved over 460 million times and still counting! (Check my math if you want, I sure did: 635 x 60 x 12200 = 464,820,000.)

So I think you can see why, for me, this Lasco 3720 has been what all appliances should be, but seldom are: simple, effective, dependable, and reasonably priced. Who knows, maybe there have been quality control problems or production changes since I bought mine. Nevertheless, the basic design has worked exceptionally well for me, and I don't think you should overlook this model if it looks like the meets your requirements.

BEST FAN EVER!
I buoght this fan at Wal- Mart and it is five dollars cheeper there than on amazon. I was looking at other reviewes and don't see how bad this fan is. It is super powerful. I love this fan! It does a great job circulating the air conditioning. THIS FAN BLOWS!

This Fan Really Blows...
...and that's a good thing :)
The Lasko 3720 is a powerful fan with lots o' cooling power.
I am not sure what fan these two other "reviewers" bought,
but the one I purchased plainly says "Lasko" on it, and the
unit inside and what's on the cover of the box are the same thing!
