I built my own, but the Redneck blind a friend has reminded me og being inside a portal potty. It seemed loud and noisy to me, but mine has insulated panels and is pretty airtight. The last thing you want it a noisy blind. I did have to add some of those concrete pads under the post this year because after 2 years of constant downward pull from my anchors, it was settling into the ground and was starting to lean.
