Product review (5 stars): Works great for my use!
Product arrived very compact and is expandable -- I use this for a fog machine to give a "Chiller" effect to keep low-lying fog. Works great for that, I assume it would also work great as a duct. No concerns about quality, definitely doesn't "feel cheap".

Will be buying a 2nd one for the same usage!

Note: I did receive this item at a discounted price in exchange for an honest review
