Maybe this was covered in the other thread but anyways...

Their platform is cast aluminum, no straight lines on platform I think they conceal nicely. I have an API that whenever I shift my feet with heavy boots on I get a ringing sound from the hollow welded tubes.
Extremely simple and quiet to set up, especially with the hook/strap.
Once it's in it's rock solid steady.
As soon as i spot an animal, I like to stand up, the seat goes up quietly and stays up.

Buy one, use it a couple times and I'm sure you will be completly satisfied!
