well it was exactly what i needed there wasnt but one thing wrong with it but that was 100 persent my fault so my big sugestion is if you have kittens dont let them play on it or sleep on it just tey not to let them near it so im thinking it just keeps getting hotter till i jus have to get up snd check it out bout half way down its ripped wide open hot air just rolling out of it

the come fast and well package, it is true to the description, I will buy again and again

Does exactly what it's suppose to do - the PVC is a big jump from the silver stuff.

Quality product, excellent packaging, worked perfectly, so much better than the plastic one I was using.

Perfect fit, improved the operation of my portable air conditioner Durable

Great duct tube

Great project duct. Delivered fast

I got a portable ac unit and needed a longer hose than the one provided. I was nervous ordering a replacement as I haven't had a portable ac previously and wasn't able to find something labeled specifically for it. This worked like a charm- I cut it in half by length and have a longer hose now with a backup but it's really well made (I feared it would tear when I was attaching it) so I likely won't need a back up.

This ducting is very sturdy. I had to manhandle it onto a vent opening (absolutely zero tolerance between the two) and was worried that the aluminum inside the ducting would tear. When I removed it to replace one of the duct clamps, I inspected the inside and found no damage. Good solid product. Deducted a star for one of the included clamps being broken with a stripped screw. The ducting itself is good.
