There are cheaper, but hard to find better quality
I normally use hard ducting, but the prices have gotten ridiculous. Plus, where you have to work around obstructions flex duct is so much easier. You just have to accept that the airflow is not going to be what rigid delivers. And as flex duct goes you can't do any better than this. Absolute top quality. I've purchase it before, along with other brands, and I just purchased this again. Forgot to install a code-required vent fan in the laundry room and I needed to work around everything that already had been installed. I got wiring run for an inline fan and needed to get from the register boot to the fan, and then to the wall vent cover. There were several items in the way so this made the run pretty easy, although I still try to keep the angles as low as possible and the runs as straight as possible. And I always fully stretch the duct to keep generated turbulence to a minimum. All that said, I really like this stuff. And it does comes with two stainless steel clamps.

High quality
I've used a lot of different ducting over the years for various projects, this is one of the higher quality, if not highest quality ducts I've used. Its expensive but worth it. It doesnt feel like its piece of tissue paper, and can handle a decent amount of abuse, at least as far as flexible ducting it concerned.

Great flexible duct!
I bought the AC Infinity CLOUDLINE PRO T8 to boost the air flow to a 2nd floor room. But, I wanted to try this out before I went through the trouble of cutting the duct work, etc. So, I hooked the fan up to this duct and ran it down the stairs and basically just blew the cold air from downstairs upstairs! Worked great!

Great for connecting Laser Engraving machines to your AC Infinity fan.
I installed this 4" ducting for use with my laser engravers. I have both the 4" and 6" ducts and have found them to fit well on both the AC Infinty fan along with a tee connection I have in my system as well. It is easy to install, and the double wall thickness design helps with minimizing pen holes that show up in regular aluminum ducting. The work great for any machine with a 4" duct and make moving air a breeze.

Good for 3D printer exhaust
Purchased to use with an inline duct blower to exhaust my BambuLabs X1C 3D printer fumes out my window. Works as expected. No complaints at all.

Best ducting that I found on the market and very affordable. 4 layers!!
Replaced ALL of my ductwork in my RV. Didn't want to take a chance when I bought it second-hand. This ducting is heavy duty. Multiple layers and way thicker than what was in there from the factory. Don't hesitate to order this ducting, you will not be disappointed.

100Φ 6m越えでコスパ良し
除湿機ほ排熱用ホースの為購入。 size 100Φ 、ちょっと大きめでも接続できた。中々 100Φで長さ6mを越えるものがなく、良い商品に巡り逢いました。 ホースの構造もしっかりしていて、かなり伸ばせて使用できるため重宝しています。
