This model does have some issues. Some have a bad bolt for the control mechanism. ALL of them have occasional whine. It comes and goes on different speeds at different environmental conditions. Not so loud that it would be a bother in a warehouse but not pleasant in a home or business.

This is a great fan and actually throws a ready good amount of air. I also noticed the noise issue mentioned by others but I solved this by opening the cage and putting some WD-40 on the part of the motor that is connected to the fan. This solved the issue and now is almost silent when operating.

just arrived and I was so excited, plugged it in and initially it was nice and quiet, sat down to continue working and "mmmMMMMMM" what the, shut it off to be sure the alien sound was coming from a brand new fan. turned it back on, same sounds. I cannot work under these conditions. This fan will be going back tomorrow sad

Bought 3 at my local Sam's club recently. I buy a few a year as replacements in a commercial kennel facility. I used to get 3 to 4 years of continuous use out of these fans. The last 3 I plugged in right out of the box had obvious bearing issues based on the noise they make. They are all back in the box going back to Sam's. Very disappointed in these new fans as we got years of use out of ones we bought prior to 2018.

Have been using this fan for a little over 6 months, it works well for the most part and moves a decent amount of air, but.....as others have said it makes a terrible chirping squealing howl noise at times, on all settings and setting 1 and 2 are almost identical in speed..I would probably not buy this again.

Super easy. Works great in the garage + we use it on our deck.

It makes a noise on the mid level

I bought this fan more than a few years ago and it still works great.

It worked for a week & quit!

Controls are on the front and it includes a wall mount. I have it on my floor and dogs love laying in front of it. Wall mount hardware included for your shop etc. I plan to buy another to gift to the neighbor.
