Definitely a quality product, very easy to work with. Ships in a box that may arrive open, but that did not affect the quality of the product. Will absolutely use again.

Mislabeled box. 7" duct instead of 6"
I'm not sure what the deal was (if someone switched the label or manufacturing error) but the box I bought had a 6in label on it and the ducting ended up being 7in. Unfortunately, I did figure this out until I dragged the box up into the attic and opened it up. At that point it just wasn't worth it to drag it back out and try to cram it all back in the back (it basically springs out once opened). I made it work, but it was still frustrating and made the project just that much harder. So try and double check the sizing of the ducting before you get too deep.

Easy to install with a screwdriver, knife, and wire cutter (needle nose pliers for the wire in the outer shell). It insulates the inner tube from the cold attic in the winter.

Product is durable and easy to work with.
I ordered two. Product is durable and easy to work with. After shaking and pulling, both were 22 ft long not 25 ft. I really missed the extra 6 feet but made it work. I got 2 10" also both were 25ft. Tip:I recycled all the insulation from the old flex duct .
