I ordered this duct based solely on the photo which shows a compact outer shell around the insulation. I need this compact design to fit in my RV due to the confined space where the duct runs. I first ordered the highest R value and when it came it looked nothing like the photo. As another reviewer so accurately described, it looked like a child wearing an x-large rain coat. This would not work in my application so I returned it and ordered the lowest R value thinking that must be what the product photo is showing. Wrong, it looked almost the same as the highest R value and absolutely nothing like the image of the product so I had to return this one also. This duct may be a fantastic product however the image shown is absolutely not the product you will receive.

Does not seem to handle more than 300 CFM
When i put 2 220 CFM units onto this ducting via a 6” x 5” x 5” metal wye. They overheat! One works great. I do not have the tools to meassure CFM but know the devices im using push a max 220 CFM this ducting meant to handle 700 CFM. I really question that. So question if its worth paying the extra money for this product, you can get much cheaper with the same R rating but lower CFM.
