Review on 💦 Compact Coolerguys 1" Waterproof IP67 12V Fan: Ultimate Space-Saver! by Eddie Man

Ordered 2 but ended up buying 4. One of the two I originally ordered had a whirring noise that came and went and the other was fine. Placed the second order of 2 and one was fine and the other sounded like sand. I have concluded that this is a manufacturing issue as it is "waterproof". Would buy again just not overly impressed with the worn/used feel of the bag as it is noisy.
