This thing really sucks!

This is a powerful little fan! The sides of my tent go concave when I turn it on full. It's much quieter that I was expecting. Don't connect the filter directly to the inlet or you'll get some vibration noise, separate with a short section of pipe.

Easy to install and well made

This is the best made dryer vent that I have ever bought. It is not as flimsy as others similar that I had purchased in the past. Comes with two heavy duty clamps, easy to install. I had ordered one of the hard thin metal dryer vents from a different company and it ripped all too pieces trying to put it on so I tried this one next. I will be sticking with this one!

Great product

Bought this and made well, thick and durable. iPower GLDUCT4X8C Non-Insulated Ducting Aluminum Foil Vent with 2 Clamps, 8-Feet 4-Inch, ProFlex Clothes Dryer Transition Duct, Fire-Resistance Coating. Strong & Flexible, Contains Corrosion Resistant Wire Helix, Temperature Range from 0 to 185+ F, Free Pair of 4-Inch Metal Clamps

Easy to Install

I needed this, a more flexible dryer vent hose, with upgraded clamps. My other one was difficult to keep on, everytime the dryer moved the hose would come off. This one is flexible enough to bend and move, as well as adjust to the length of space between the connections and the wall vent.

4" inline Fan

Fan can move some air, Speed controller is nice to have. Turned my 4x4 tent into a vacuum chamber. GREAT customer service, if you have an issue they will help!

Nothing special about this product beyond it saved me the hassle of going to Home Depot (which is actually a really great thing!

It works exactly as intended. Nothing special about this product beyond it saved me the hassle of going to Home Depot (which is actually a really great thing!!!)

STOP & READ THIS REVIEW - I'm a BUDGET GROWER!

If it were up to me my diet would consist of ramen noodles, and potatoes. Only because those are the two cheapest things on the planet I can think of, and I would probably grow my own potatoes (speaking of which, I do grow my own tomatoes, onions, chives, and various other green veggies....) I've purchased cheap lights, cheap tents, cheap grow medium, all in a vain effort to find a 'good quality balance'. Hardly ever happens. But this.... Look, I've actually built a carbon filter from scratch, and it worked great, thing is... It cost me MORE than buying this unit did. This unit, OUT PERFORMS what I built from scratch (engineering background), now, its not as quiet, but its also not loud, I'm willing to bet if I had it properly mounted with rubber bushings, it would be next to silent (it is not properly mounted, it is sitting on a wire rack *increases the amount of vibrations*) I have been growing for a very long time, for personal consumption, I have had several issues with odor, even after I built my own filter... Since installing this thing almost a year ago, there have been no problems. There is a filter cover that comes with it, you should hand wash it and let it drip dry, and the filter itself is actually very easy to swap out with a little practice. This is a great buy, I will recommend this to my fellow growers, as well as you. If you want strong and healthy plants, without the odor, this works great! Pro Tip: If you are running Co2, run the exhaust of the filter back into your tent, it'll keep your temps raised, and you won't loose any Co2

190 CFM Fan, 8 Ft Duct and Speed Control - All Five Star

So Amazon needs to get their act together when it comes to having multiple items on one page and you can only review one item versus each one separately. Makes reading the reviews a PITA too. I have found this in other areas as well. Come on Amazon - get your sh*t together. Okay that said, I purchased the iPower 190 CFM 4" fan, the 8 Ft x 4" aluminum duct and the iPower Speed Controller. I am using all three to vent heat and humidity out of a 4' x 11' grow room that is inside a 11' x 11' bedroom on the 2nd floor of my home. Just setting it up since most grow rooms are in basements. iPower 190CFM Fan: I have the fan mounted in a vacant room adjacent to my grow room. It's actually in the closet in that room. I mounted it to the wire frame shelf using plastic wire ties. So that says a lot about the vibration level of the fan. It runs very smooth and is relatively quite as well - and it's not too heavy. Now if I had it in the grow space where I already have the noise of the light fans (x5) and oscillating fans, it might add to that, but not enough to make it overly loud when working in the room, or when the door is shut. I did not want to mount it in the grow room as I have already taxed the power available in there for lighting and running a heater - it's cold in MI right now so a heater is sometimes needed at night when the lights are off. I have it on a timer so it runs on and off during the day and comes on a few times during the night too. It pulls the hot air out very quickly and that is on Medium speed using the speed controller, and has really helped stabilize the humidity levels. I am still working on the exact times it needs to run and speed, but it does a great job. Oh, and as mentioned by another reviewer, it runs more quietly when on full speed and not regulated. Just a thought if noise is an issue for your setup. It's very well made and like I noted, it runs real smooth and quiet and has a real strong draw to it - even on medium. I was not sure if the 190 CFM would be enough, but my demands are not high so I figured I'd start there and go up if need be. So far it seems more than adequate. 8 ft Flexible Duct: I am using this this with the iPower 190 CFM exhaust fan to draw the heat and humidity out of my grow tent. It came all compressed into a small package which was convenient. The two clamps included are not cheap, but good quality clamps. I used it to go through two sheets of drywall near the top of the grow room space and the other end connects to the exhaust fan in a spare adjacent room. I have it temporary taped in place until the 4" intake vent I purchased arrives. I did not need to extend it to the full length so having it compressed made the installation a lot easier. I did not have to cut it so I can extend it later if I need too and I don't have a length of hose to deal with in the mean time. Other than that, it's a pretty standard coiled aluminum duct - maybe a bit thicker than some I have used, thinner than others, but about what I expected at this price. If I end up venting it out the window, I will be buying more of the same hose. I have something similar on my dryer, which I recommend versus the plastic type to prevent fires, and this one seems a bit better grade then another one I purchased at Home Depot. Definitely easier to work with in the compressed form. iPower Speed Control: Not much to this item. I was not sure if I would need to have the fan on high speed so I figured I'd get this just in case, and considering the low price it was worth the little extra money. It's made by the same company that makes the fan so I am not concerned about it harming the fan motor. I have it plugged into a 24 hr mechanical timer that is divided into 15 minute intervals which allows a lot of flexibility. I wanted a timer that plugged into an outlet and allowed the speed control to plug into that. If you are setting something up in a similar configuration than I would recommend this timer: https://www.amazon.com/gp/product/B07JLS13SY/ref=ppx_yo_dt_b_asin_title_o02__o00_s02?ie=UTF8&psc=1 It's the only one that has the outlet in the face so the timer can plug in and not get in the way of the rotating timer face. It worked out real well. So yeah, the speed control does what is should do - controls the speed of the fan. In Summary: I can definitely recommend all three of these items for anyone who has similar requirements.

Great for bathroom ventilation! My wife says I should have gotten the bigger fan though!

Had to get this and a 4" duct fan, both from the same company, and installed it just fine. The vent, for some reason, seems thicker and more durable than the ones you find at your local hardware store (and also cheaper, just so ya know). I installed it just fine, bathroom vent works great now and I have absolutely no complaints. Really, though, it doesn't take a genius to run these flex ducts- but it does take experience to pick the proper quality duct that will last for a long time and won't split, rip, tear or ripple during installation.

Did the job.

Once I finally got around to stacking my dryer on top of my washer, I needed to get a longer vent. I loved it. It arrived all compact about 5 inches, and easily, smoothly, flexibly stretched out to 8 feet. The foil IS quite thin and fragile, so handle with care as to not rip holes in it. It is about as thin at aluminum. Might not be a good choice if you have pets or children that can get to it. But for me, it is perfect. Simple to use with one small flathead to tighten, no little screws to lose. I appreciated the simplicity, the light weight and easy to use. My old one was made out of sturdier material, but was also more likely to cut you around the edges, also more awkward to maneuver and deal with due to its thicker and stiffer materials.
