Good quality. Very quiet.

パワー感は、どうかな？ と、いった感じです。

The brand is one of the better manufacturers selling to the general public and the vendor was very supportive and provided prompt service. I would buy from them again and recommend the inline fan without hesitation. It’s quiet at lower settings and works without issue.

I replaced a built in fan in my kitchen extractor unit (failed motor) by mounting this unit in-line in the extract duct. The remote lead was long enough for me to mount the remote in my old unit and yet have the fan mounted well away. I mounted the fan on wires thus reducing any transmitted running noise (I would not expect much anyway as such a smooth running motor). The level of extraction is variable and perfect for the application. Excellent product 10/10. Fully recommend.

This inline fan works great — super quiet and powerful, exactly what I needed to improve airflow in a small space. It moves a lot of air without the loud hum you get from cheaper fans. Installation took a bit of fiddling to get everything sealed properly, but once it was set up, it ran smoothly. Really happy with the quality and performance.

-It comes with the right power plug for EU(for 220v), even if the original images of the product don't show it(i think they are old), it looks like in the past wasn't the case because of others reviews, but now it comes with the right power plug -The cables are long, i mean, looong(power and controller cables), 2,5 meters for uis cable and 2,3 meters for power cable -I took photos of the manual only so you can see: +installation in different scenarios +cleaning +you can see its an actual useful manual +and the warranty part makes me feel like they really care -It comes with every screw, strap and little thing you need to install it in all possible scenarios(see the photos) -If you want to get noise test you can go to amazon.com(eeuu version) and see the videos on the reviews, my phone mic is trash so I wont do a noise test, but I can tell you that at level 1(it has 10 levels) makes 0 noise, at level 5 its the maximum I can deal with(and need) and above looks like its for scenarios where you really need to ventilate and dont care about the noise, so it gives you options, from 3 to 5 in my case is enough(I will never go above most likely) -I like the philosophy of "its yours, you have the control: you can fully open it(normal screws), you have all these intensity levels(from 1-"it barely moves" 2-"quiet and performant" to 3-"hold on to something, this airplane its gonna liftoff", you have a detailed manual, you have long cables, in the box you have all needed screws and little things" -btw the fan is exposed...not a bad thing, its made for people that think a bit
