Quite noisy but works fine & is dual speed.
This fan is noisier than others i've got but it works verry well & it's also a 2-speed fan that can be wired through a standard dimmer switch for a completely variable speed & it's inexpensive so good value.

Brilliant value
Great little extraction fan. I bought this as my tent was getting hot in summer and thought I would get the added bonus of sucking out all the stale air inside the tent amongst my plants. Well it has worked for both those problems. The tent dropped 4 degrees in temperature and I've just finished this particular project and all the plants were visibly more healthy than usual when comparing this to without the fan. And don't be worried about noise either. It's incredibly quiet. My tent is in bedroom. The fan is on a shelf outside the tent and connected via extendable ducting. It's so quiet it doesn't affect my sleep pattern one bit. I have never been woken up by it or struggled to go to sleep while on either. Great little fan! Will buy again!!

Good but not perfect
Good little fan. Price is great for what you get but it is audible and does not have three speeds as the specs say.

Good for small volume of air, not very powerful.
This isn’t very powerful at sucking air. Attached a 3m hose to it and the suction at the end of that seems lower than at the actual fan duct inlets. I’d say it’s good for a tiny room about 2m³, grow tents, general dust extractor… The noise level is very good, quiet and even quieter with a pvc hose attached. The sound at the end of the hose is silent. The fan unit does make a slight rattle and the motor sound can be heard. Also it vibrates if the motor plastic housing touches anything. Good budget extractor fan, good value for money compared to others. Easy to install with standard size diameter inlet & outlet ports. Also the casing clips off with two clips, so you can access the fan blades and service / clean the fan and motor etc.

Perfect for 3d printing.
I use this to extract fumes from a grow tent my 3d printer is in. It's a little loud but once your out of the room and the door closed you won't hear it. Extremely effective at clearing out the fumes.

Clear that air this is the perfect choice!
Very quiet and very powerful, I was impressed, compact and effective. I'd recommend it.
