Misrepresented
Because the product description says "3-4-5-6 inches" I assumed that I would be able to use it on my project that needed a 5 inch diameter. I was wrong; not any part of this piece is 5 inches in diameter! I wasted my money on a piece that was misrepresented in the description.

Needs tape measure approval
Not sure what tape measuring device the seller uses but not an American one

it is not a coupler
This reduser doesn't meant to be used co connect metal duct to the flexible one. External diameter is exact match to metal so it can't be inserted in or stretched over without extra effort.

Home Made Airbrush Booth
It didn't work for me because my "engineering" of the booth was too complicated. Wanted to use it as a duct reducer but basic issue of mixing metric and inch dimensioned duct components was problem

Does the job for intake of AC portable unit.
Bought to add intake for portable AC unit since nothing similar at hardware store. It thin so only used aluminum tape to seal end to hose. Cut to slip into portable AC intake opening.
