Brown Duct Calculator

While I really wanted the product and did not return it, I was disappointed that it was damaged when I received it. I paid too much for a piece of cardboard that was improperly packaged and creased badly when I received it. Brand new should be brand new, not creased and kinked so bad I had to try to press it between large heavy books to get it flat enough to use the rotating scale. I guess I should have purchased the Trane Ductilator after all.

This is a nice duct calculator for sheet metal ducts. I was hoping it was one for calculating other types of duct as well. It is lamented cardboard so it should hold up.

Came bent. Works fine otherwise.

So disappointed when I received it it was bended almost ripped can I use it now it won't even turned a little well definitely will not give it no stars I am so disappointed with this product the only reason I gave it one star as because I have to put it other than that I would have gave it no stars

I found this duct calculator to be simple to use and easy to use. I will look forward to using it in the future.

Worked as described

Fast and Very simple to work with.
