Review on Enhance Air Circulation with the Vornado 133 Compact Air Circulator Fan by Justin Jefferson

It has been about a week since I bought this fan on sale. I always have a desktop fan on all my computers and they run almost all the time. I bought this for the same purpose and it fits nicely under my VESA mount iMac. The only problem is that after running at high speed for about a week for most of the day, the fan starts making some rattling noises that were unpleasant and distinct when it was new. I can't hear it at low frequencies, but at high frequencies I definitely hear a vibration that wasn't there a week ago. For now I'll let this play while it's in its return phase, but I'll probably bring it back at the end as I don't want this thing to fall down on me. Disappointing as I have different USB brands. Desktop fans that I leave on all the time and last for years. This one that replaced one of them (still works but not as much airflow) degrades after a few days. Not very happy with the quality. Maybe I have a bad apple, or maybe they're just not designed to run at high speeds for more than an hour or two at a time, which to me is a design flaw. EDIT - 5 months later. Although the device still produces slight vibrations/noises at high frequencies (difficult to describe), they are still getting strong after 5 months. I raise to 4 ⭐️.
