Review on Premium Calimaero VKE 5-Inch Stainless Steel Air Vent Louvre With Gravity Flap Grille by Jeff Gopala

regarding the 6 inch vent: like another reviewer stated, it's not 6 inches at all. I thought I could modify it for a bathroom exhaust fan but it's not even close. It goes from 5 1/4 on the interior side to 5 3/4 inches ID closest to the flaps but it's still not workable for a 6 inch exhaust vent.Suggestions for the manufacturer:1) post an image with the ACTUAL dimensions.Or.2) call it a 5 1/4 inch vent.Or. 3) make an actual 6 inch vent.4) I would pay double for a well built vent cap that actually fit (and worked quietly.)Having read more bad reviews after buying it, I'm glad to be returning it because it looks to be noisy and the metal is cheap junk. Also the metal edges are sharp and cut skin easily.DO NOT buy this.
