They are very good fans as long as they work when you get them good air flow, somewhat quiet mostly wind noise which can't be helped, if the power usage is correct then they are good on power to but we will look into that later because vevor can use some misleading sales tactics like giving you rating on the lowest setting so we will post power usage onces we test it I'll update this review. That said in my experience beware of the following. originally we ordered 3 of these fans which only 2 worked vevor sent us through hell trying to get warranty and it was never used which took over a month then when they finally warrantied it they sent us a smaller 6" fan as a replacement which was completely useless to us and very disappointing and we had already been ready for the 8" fan we ordered that never worked, which led to us ordering this one because we needed a 8" but we are glad vevor showed us warranty wasn't going to be so reliable nor easy. even when it wasn't half a year later this was right away broken because we were looking at large amount of vevor solar batteries and all supplies but if it's hard with this fan at such a low value I can't imagine it'll be better with hundreds of thousands on the line and we had heard vevors warranty was promising and good, sadly not our experience currently reduced stars on the overall for the hastle and hussling us out of 120$. We paid for 4 but only got 3

Controller screen burnt out in first five minutes now its useless !

I picked up one of these fans due to its high airflow and rated static pressure rating of 300 Pascal's. The fan, as delivered, is only able to achieve 100 Pascal's of peak pressure, at which point the airflow drops by a factor of 10. I intended to use this with a filter as a low-noise fume extractor; but due to the very poor pressure handling (which I shouldn't be surprised at with a 68W power rating!) it's completely unsuitable for this application. In its intended use of home or small-space ventilation, with sufficient make-up air to maintain a sub-100 Pascal pressure differential: it does absolutely meet and exceed it's 800CFM rating. Had I used is strictly as designed: it's a pretty decent fan! For my purpose, the fan is rated incorrectly and this should be updated.

Forgot to put the controller in the package
