A good piece of kit. A little fiddly fitting it but does a good job of insulating the a/c tubing. Can be folded back on itself to shorten the length. Stiffens the tube with the extra insulation, so makes it a bit of a job in small spaces. Will reduce the amount of heat coming out of the tube in the summer, making the room warmer. Will reduce the cold air influx in the winter. Altogether a good purchase 👍.

Works fairly good to keep most of the heat going outside

Why did you pick this product vs others?: Works great! Easy to use. Able to fold it back on itself if the hose length shortens up for positioning.  The straps make it stable and won’t budge. Great insulator form the heat coming through the tube.  Buy 2 if you have a two hose system. The intake gets hotter than I thought it would, and this takes care of that. Makes a difference in the radiated heat from around the  a/c unit.  Easy to wrap around the tube, 2 Velcro positions that run the length of the wrap in case your tube is smaller. Will buy for my other a/c unit in the garage.

Does the trick , would buy again

It does its job to keep the heat inside the hose very well ,but, it doesn't ben a lot as you can see on the picture. The main thing is that the heat doesn't comes out as it use to without that item. would of been 5 starts if that material would of bend a bit more. Overhall it's a good product.
