Review: Works good - clamps aren't good though - This flex duct works good. Easy to install. The outer aluminum wrap is thin but doesn't rip easily. It's easy to cut using a razer. The insulation is decent. The clamps are no good though. The quality of the clamps is fine, but the screw takes a lot of effort to move. I ended up using large plastic zip ties instead of the clamps. Overall I'm happy with this purchase. Packaging was very good.
Review: A good product, but a pain to thread through the ceiling - So whoever built my house decided to install a bathroom fan with no vent to the outside. Naturally, I had to correct this but that involved threading this duct through a pre-existing ceiling - 15 feet then a left hand turn then 15 more feet to the outside. This product made the journey. It's a sturdy duct. It got dragged over rebar, no problem. It handled being tied to a dryer brush, no problem. The outside never tore. The metal rings never got bent out of shape. It's so sturdy that it was kind of a problem, since it could NOT squish its way past pipes and wires. It also stops dead if it hits the pointy part of a screw. It doesn't rip, it just get caught then refuses to move. Because of this, I ended up having to open the ceiling in one spot to get it around a big pipe and two exposed screws. For anyone looking to do a similar project, I recommend using the smallest duct possible (I bought 4inch but I really wish I had bought 3inch). I'd also reconsider using an insulated duct, as the insulation adds two inches to the width of the duct and it doesn't squish down as much as you'd hope it would. And use the dryer-vent brush strategy for getting it through your ceiling. First, thread a long dryer-vent brush through the ceiling, then tie the brush end to the duct, then pull the other end of the brush - thus dragging the duct into the ceiling. But I'm glad I bought what I did. In the end, there is surprisingly strong airflow through the duct (I bought two and connected them to go the distance), and I credit the insulation with tamping down noise from the bathroom.

### ⭐⭐⭐⭐⭐ Simple if you know what you’re doing.
*by L***N on March 7, 2026*

I recently purchased a home. After being in it for a year or so we’ve come to notice it was a flipped house. One thing we noticed is our upstairs was not cooling right in 2 of the bedrooms. Checked the vent and no pressure. Followed the hvac lines and someone thought it was a great idea to split a 6in into 2 rooms. Ran another line to the box with this flex duct and better flow, cooler rooms, happier hvac.
