Rated 3.9 out of 5 by 15 reviewers.
Rated 4.0 out of 5.0 by Better than the regular "Weather Shield". This is an inexpensive box fan, but it works great as we have no A/C. [] We stack two of them in the window w/o the legs and secure them with a bungee. [] We need one fan per 100 sq ft on hot California days. [] I like the larger selector knob. [] It is only a couple of watts more than the original. [] If you like box fans, get the WEATHER SHIELD PREMIUM PLUS. [] But remember, this is a machine and you should not drop it. [] As usual, The Home Depot ships quickly for only a few dollars, or free. August 14, 2013
Rated 5.0 out of 5.0 by Used for Garage fan Quiet in low speed. Good volume of air and light weight December 10, 2014
Rated 5.0 out of 5.0 by Excellent value for the money! This fan moves a lot of air and the three speeds are handy also. It is fairly well made and with care should work through a long hot summer (at least). It is light and easy to move around and I added 2 attachments and have it hanging from my shop ceiling and remove it when I am through working there so it won't get dirty. For the price it is a good buy. May 24, 2014
Rated 3.0 out of 5.0 by Noisy and unstable Fan has limited features for the price. It's just a basic box fan, that's it. The fan itself is very loud and noisy. I have to keep it on the lowest setting if I use this at night while sleeping. Also, I'm severely disappointed in the stability of the fan. It has a tendency to tip over when brushed against. It is not the most stable unit I have ever owned. It seems top heavy thus contributing to its tendency to tip over. This would be an important consideration if you have little kids.. Overall construction is very good and it seems well made. I have had good luck with Lasko products in the past. hope to get plenty of service out of this unit. I'll recommend the unit with reservations due to how loud it is at higher speeds. December 18, 2013
Rated 3.0 out of 5.0 by Low price but poor quality. The fan works well and is quiet but the whole thing is cheap plastic and will not last for very long. Whatever you do, don't drop it. August 12, 2014
