Review on 🐠 Adeeing Portable Mini USB Aquarium Fish Tank with Oxygen Air Pump - Energy-Saving Mute Operation, Supplies & Accessories by Wine Gray

This small air pump is very quiet. I usually don't know if it works until I touch it. It produces a very minimal, low noise level that is easy to ignore. The air volume is not large, enough for a small fish tank. I drove for a month without stopping. Turned off twice. After I turn it back on and it works. I don't know how reliable it is, but I don't expect it to last more than a year. However, for the small price, the performance is better than I expected.
