Purchased for a portable AC exhaust hose replacement. Works GREAT! Gets barely warm to the touch, when the old exhaust hose was extremely hot and radiating heat back into the room. AC is a little quieter too. Can't recommend this insulated duct highly enough, I can't believe I had been undermining my AC's efficiency for years with a non-insulated exhaust duct.The duct itself feels very well-made, each end has a short length of reinforced foil which fits under the included hose clamps perfectly. Insulated outer duct begins a few inches later, and the outer duct material feels very durable and flexible. The inner duct acts as the support and the outer duct holds the insulation in place, and the result is a dramatic drop in outer duct temp. AC has been running for a few hours now the outer duct is no hotter. I think we have a winner.

The stock hoses for my portable (two-hose!) air conditioner had disintegrated, and I've long been considering buying a set of insulated hoses for it ever since I bought the unit.I'm honestly surprised that they were not insulated at all out of the box.As such, I bought two of these hoses in 6"x8'.Installing them onto the original hose adapters was a bit of a task, entailing very liberal application of duct tape.This done, I connected them up and powered the unit up.I did not buy these hoses with the intent of being quiet, but I was honestly and pleasantly surprised by how much quieter the condenser side fan was now. I can barely hear it anymore, and it quickly subsides under the sound of the compressor once pressure builds. With the original hoses, it was easily the loudest part of the entire air conditioner.I cannot measure the thermal performance directly versus the original hoses, due to the original hoses having disintegrated years ago as of me writing this review.However, I can definitely say that, before, it was actually hot behind the unit. With these, it's significantly cooler, and the unit's performance has significantly improved. It can now actually cool my garage! Something it used to struggle with.The hoses have also survived from a durability standpoint significantly better than the original plastic hoses. Although they ARE a little less convenient to store when the air conditioner's not in use thanks to their bulk. That's the only "negative", other than the admittedly improvised installation, that I can even say about them.Final Answer:If you have a portable air conditioner and use it with any regularity, upgrade it to insulated hose(s) now. You will not regret it.

Product is sturdy but no claps came with it and also says it can be stretched out to 8 feet that's a lie!

I bought a different insulated vent hose, by the same company, it worked well, but it did not provide the insulation I had hoped for. This one has a noticable impact on radiating heat, as well as noise. The latter was a surprise bonus, that I did not know about. To be honest, the unit seamed fairly quiet, now it is quiet. I have a 4” exhaust on the unit, and just used a reducer coupler, to make 4”. The additional 2” takes more room, but removes more hot air.** I later added a Infinity in line exhaust fan, to help pull the hot air out through the vent. Adding the fan had the greatest impact on any heat the insulation missed. They make them in variable speeds, and they are priced reasonably. I have a 2 degree difference from air temp to hose temp now.

Worked great. Feels like quality. Slightly disappointed with the ends. Foil separated but clamped as one pice. Could have been more gentle. 1st time. But workers great for noise reduction.

Work good. Alittle costly. Just a note that the ducting ends will fit 4". But is more like 6" with the paddling around the body. Will not fit a 4" hole But the ends fit 4".
