    • Easy to install - works great
Size: 4 Inch
Easy to install - works great. I used it to vent a basement that has no window. Adjustable speed. really moves the air. very quiet... much more quiet than I expected.

    • Superb little fan
Size: 4 Inch
Bought this for a 2x4 grow tent to provide cooler air through the bottom porch in the tent. Does an excellent job of doing this. So quiet can barely hear it and the adjustable speed is very convenient as it is almost cooled down more than I wanted it to so all I have to do is adjust the speed to control this. I will buy this product again in a heartbeat. Not to mention the price can't be beat. You would be surprised I just how much air this little fan moved not only 4 in. ... show more

    • Lightweight, speed control is a great feature. Buzzes
Size: 6 Inch
I used this fan to replace a metal crawlspace vent fan that was rattling. I like that it has a speed control I can adjust (and save energy) depending on how much moisture might be in the soil under the house. Installation was easy (although I installed an outlet in place of the direct wire of the old fan). The fan is fairly quiet but has a buzz to it. It's a frequency that must penetrate as I wrapped it in insulation and it didn't change much. ... show more

    • Very cool product. Cranks out the air! Love the adjustable speed. Hard to find pipe that fit.
Size: 3 Inch
I bought both this 3"and the 4" version to test out for my camper van. One I will use for my composting toilet. The other I will use for air movement in the main living space until the AC cools down the van. The 3" is a little louder than the 4" but the 3" cranks out way more air than the 4". You can always dial back the 3" to a very quiet hum and even with the lowest speed setting, you get plenty of air flow for the composting toilet. Since the toilet is also in the sealed shower room with a large ceiling, I will need more air vents from outside the room so that when the ceiling fan is on, I can crank up the 3" to avoid back flow air through the composting toilet. The 4" fan is nice but I almost want to use the 3" fan for airflow in the main living space since it makes a better breeze. Even though it is a little louder. The noise is not really bad. Slightly more than the AC noise. only due to the higher frequency which you can turn down as needed. the 3" needs 2.75" pipe adapter to MSTR with a 2” pipe. ~$10 each. https://www.amazon.com/gp/aw/d/B0BQW8W49Q/ref=ox_sc_act_image_1?smid=A34RJ9S07AUY15&psc=1 ... show more

    • Great little fan!
Size: 6 Inch
For the price, it's perfect. The blades are a little brittle, but as long as you don't let anything get in there you'll be fine. The speed control is really handy, sometimes it takes a second to recognize it's turned on, but that might be user error. Either way, I bought 2 and they both are pretty quiet for the most part. Air flow is great, and it is simple to use or fit wherever your needs are. ... show more

    • Does not vent heat well
Size: 4 Inch
Don’t use this if you intend to vent high heat. I bought this to vent my portable AC to make it vent hot air faster. This fan worked for a bit but then it kept over heating and shutting off, and I had to let it cool down for a full day before it would turn on again. It shuts down really fast if you use it on max speed while venting hot air. After a few months, it stopped working all together and I had to throw it away. It’s not good for high heat. I recommend buying a heavy duty full metal one if you intend on venting high heat. This one is mostly plastic so it’s not good for heat. It was nice while it lasted though. I like the look of it and I like the power knob it came with. ... show more
