20" Weather-Shield Performance Box Fan, 3-Speed (3720)

I have this thing on 15 hours a day, in use for a CR box. It reliably runs at any speed.

This fan fell apart immediately. The handle broke, it started rattling, and all three speed settings now move as slow as speed 1. It falls over easily even with the feet installed, but the feet broke on mine so it’s basically useless! This fan is an affront to the environment, your wallet, and the Lasko brand. Shame on the seller and shame on the company for making such a garbage product and pricing it so highly! This fan wouldn’t even be acceptable at 15 dollars!! When I requested a refund the seller said “the best I can do is give you 50% back”. Shame! Shame! Shame!! Update: I have continued to use it, and now it's SMOKING. This thing is a FIRE HAZARD!

I am partial to this brand and have had good luck with longevity of products. This fan is quieter than the older models and very efficient at moving air. Easy to use and quite sturdy. Would recommend this product as it is for the floor a window or on a shelf.

I bought 2 of these fans. I use them everyday, mainly to sleep with...almost as a sound machine. They also work great for their main use...keeping my house cool and myself cool, I don’t use my air-conditioning unit...just open-windows and fans. I spent an absolute total of $78.40 for 2 of these, and overspent by $10.40. Long story, but I should not have spent more than $68.00 total for these 2 fans...Amazon and 3rd-party supplier / seller got a better deal than I did. The fans work great, no issues there, everything is swell...Lasko makes great quality products. I was not happy with the packaging...the 2 fans only came in the actual fan box themselves (see photos), no additional packaging...they easily could have been damaged in the delivery process...no (and I mean zero) additional packaging or boxing, unbelievable. It all worked out though, a couple very small manufacturer scratches on the frame metal, nothing too major at all. I recommend this fan, but paying more than $34.00 total per fan, look elsewhere...at least give it the due diligence to hinder any buyer’s remorse. Great box fans though, I recommend this exact box fan.

Got it free shipped within 24 hours. Just simply plugged and the fan started running. Just make sure the fan is on a window with back facing the open window. Three speeds good enough to cover a room of 10x12 ft. Quality is good and sturdy.

Fan was sturdy, nice looking but reading the fine print on sticker, not supposed to be in window, bathroom or near water. Intended to use in attic window for exhaust at night, and not intending to have to bring in whenever raining. Not sure how it was to be 'weather shield'...returned it after trying unsuccessfully to contact company for clarification. Not willing to take a chance, as sticker made it clear that there would be no responsibility for shorting out, etc. Otherwise, using inside room or to dry basement, etc would be fine , I think. [placement of button on top would have made adjustment necessary if in window frame, as well]

This is my second Lasko Weather Shield, my first one lasted quite a number of years and I run it all night most of the summer. Made of steel, not plastic, has feet that fit correctly to stabilize it. Makes a great floor or window fan. I trust this brand.

The fan was initially fine; I'd had Lasko fans previously and never had any problems but this latest one has proven to be troublesome; there seems to be a vibrational rattling which mysteriously comes and goes. I have tried to use it as a window fan but it has again started acting up, even at the lowest speed. I will put it in a closet and hope for a refund

Seems sturdy and might have good airflow, but it was so loud on the lowest setting, I returned it. Customer service was fairly good, though.
