All of the Opolar fans I have are just great. Different uses, camping and outdoors I have the rechargeable fans. This is my first USB fan. Only 9 inch but puts out a good amount of cool air, and on low you can run this fan for 250 hours and it will only cost you less then a dime. I have found that The USB fans are louder, but they spin faster, and it's not really that loud, cant hear it over the TV. and I fall asleep no problem. Not silent, but very quiet. I don't understand Any bad reviews, these fans are fantastic.
I have enjoyed using this fan ...
Great product, can't say how cool enough.
I bought this fan because it was praised on YouTube as being so quiet it could be used inside a recording booth even during takes. No way. It’s a decent little fan and being USB is handy and it is relatively quiet. But it is not nearly as quiet as it sounded in the YouTube clips and there is no way it could be used during a recording.
I purchased this with the high reviews of it being quiet. This definitely isn't quite and when I asked for a return or replacement I was told I'd have to pay for the return shipping.
NOT HAPPY WITH OPOLAR!
