Review on 🌬️ Ultra Quiet 4 Inch Small Desk Fan – Powerful Airflow, USB Powered, 3 Speeds, Adjustable Head – Ideal for Office, Study, Bedroom by Brett Zhu

I bought a pair of these fans with another company's logo last year and really liked them. They are incredibly quiet and move an amazing amount of air. The other company no longer exists and this fan looked exactly the same in the photos. . . when it came, it is indeed the same fan. Plugged it in and noticed a very faint rattle. . let it run for a while but was surprised when, even though it was running at the lowest speed, it suddenly jumped to a higher speed. I reset it to its lowest setting, but after about 15 minutes it jumped back up to a higher speed. . . returned!
