Fan
It's as described. Does the job depending on what you're expecting I guess. Is pretty quiet, Light weight . Does NOT have on/off switch so keep in mind if that's an issue. I'll use it as a movable fan in my small building. Not bad for price . 👍Verified purchase: YesCondition: New

TRASH!
I am an HVAC tech and i used my CFM meter after attaching to just a few ft of duct and it dosnt move any air. No where near CFM stated on description. spend a few dollars more and get the $60 metal housing ones with the little vinyl cover that goes over it. only thing is it is quite but that makes since because it is ALL PLASTIC and has a weak little under powered motor. AGAIN, DO NOT WASTE YOUR MONEY!!!!Verified purchase: YesCondition: New

Great little fan.
Works great! It leaked around the seam a little bit, but I covered it with some duct tape and seal it up. Very quiet and moves plenty of air. If your looking to not spend a bunch of money, I suggest going with one of these. It should get the job done.

Solid preformer, great value.
It's quiet, works flawlessly and endlessly. It doesn't work with speed controllers, it will slow marginally and then stop dead and hum/groan so this fan is full speed only. It preforms great at full speed however and I am very happy with this, so much so that this is my second one. I have 1 on the intake with a modded/hacked house filter and the exhaust one is hooked to a carbon filter. I have another fan I paid more than twice as much for and it slows nicely with a speed controller but it maxes out at 100 CFM so I must say it again ... I am very happy with this fan.Verified purchase: YesCondition: New

It's a decent fan. Read
I got this to boost a 120v dryer that its blower went out. It worked great for 1.5 months for that. I did exceed its heat rating slightly. But the 4/5 star doesnt have to do with that. Cfm rating isnt accurate. But still good flow for grow tent (I've grown before) It's because the casing is very loose. Falls apart. If you use some black electrical tape to tape it up...its perfect and enhances flow.. The high heat or vibration also caused the fan blade to come off the shaft. And bind up and luckily I was at home and heart it to unplug it before it burned. I superglue the fan duct back on and it's still trucking along. I know this is likely due to the heat... But it still needs a better locking case. That has nothing to do with heat it's not properly sized plastic and the locking twist snap is very short. So one little squeeze and it pops apart. Overall it's a good fan though. Put tape on it and grow away!!!Verified purchase: YesCondition: New

Tent worthy
Great little fan that cooled my 4-2 tent and is very quiet. Probably not suitable for a small grow room but it will try really hard! I would recommend this fan and the only thing I would say is buy the speed control unit to make this product even better.Great dealVerified purchase: YesCondition: New

Yay! They arrived! With someone elses birthday notes. Haha
Though they came with birthday notes for someone else. I was surprised in how small they are. My old fans are twice the size and pump the same amount of air with double the elctricity consumption. Look nice and run quietly. Looking at others reviews I hope they continue to run quietly.Verified purchase: YesCondition: New

Great fan but it is NOT 200cfm. It is simply the 195cfm model. But the 5cfm does not make a difference.
This fan is simply the 195cfm model. But it is super quiet, and efficient. It will clear the odor 100% of a 2x2 or 3x3 (with carbon filter) within an hour. Or simply exchange all of the air within 5 minutes. For the price, you can't beat it. I definitely would recommend this fan for any small grow. A 6" is not needed unless you're running a cool tube. And even then you could get a 6"to 4" adapter and it will do the job just fine.Verified purchase: YesCondition: New

Blowing a "radon" out of house
Running a few days. Used to blow an air from the sump well. More cost effective than any other Radon fan. To evaluate reliability is to soon. Time will answer this point. The only delta is that it doesn't with to 4" PVC pipe.
