Product review (1 stars): Very poor quality
We needed this for a straight run of about five feet, but right out of the package it was cracked in a couple spots. No problem, we thought, we'll just tape over it with the duct sealant tape we have. But then the ends of both sides began to unravel as soon as we slipped the clamps on. Again, we were doing a straight shot, this line would have no bends or angles. There's no way this can have any bend in it without serious malfunction, especially if it can't even handle installation. We will be returning this.
