Good price! I've always had great luck with Lasko products being well-made and long lasting.

These are un-killable. Even if they fall down a flight of stairs, the only thing that breaks off is the feet.

Back before tariffs/scamflation, these were always $15 for the ACE 4th of July sale - nowadays this is a great price

Made in USA !

Buy it, you won't be sorry.

I bought one of these years ago. It's had a wobble since day 1. It walks itself across the floor. If I say anything more, I know I'll get downvoted.

is this a popular model for a CR box?

Menards has an "Aerospeed" on sale for $16.84 and you can get 11% store credit rebate.

I have one and it definitely walks across hard floors. Not bad for the price though.

Can use the $10 off $35 order code at Walmart to get the price down.

I have one and it's a great window fan. Really cools down a room. When I went to Walmart to buy a 2nd one recently, they were sold out in store. In for 1!

I have 3, they all do that. Luckily, I mostly use them in a windowsill.

This is total bs. I purchased 4 of these a month ago from Walmart. All brand new. They each have fallen over once. Each fan broke in various ways. One of them one blade completely came off as a result of it just tipping over onto a rug. The other 3 all run considerably slower than they did for the first week. Others when fell onto the ground shattered the edge frame which broke away. Another one the speed control dial completely came away from the housing. The last description I would label for these fans is un-killable. Instead they are some of the most fragile household products I have ever owned.
I am convinced that Lasko has an army of paid folks out there…..
