Okay, here are some of my thoughts on the chair.
First off, I want to say thank you for the very kind offer to let us all try this chair out. An incredible gesture.
I will start of with some of the pros.
Probably the best feature of this chair for me was the ability to adjust the legs quickly and quietly for uneven ground. The large rocker type feet allow the chair to be stable on really steep uneven ground that no other chair comes close to IMHO. The chair is built like a tank, and I think it would take quite alot to damage the chair. Previous concerns about how difficult it is to transport the chair really didn't pan out for me. It is far easier for me to carry this than a treestand. I found the seat to be pretty easy to setup, without instructions as well. The seat swivels quite nicely, but I will get back to that, later.
Now for some cons.
The seat was comfortably enough for me to sit for a few hours tops, but if I was going to sit for longer than that, I would definitely need to bring and extra padded seat or something. Not that there is any other seat available that accomodates that.
This biggest issue I had was that the seat would make noise when I put weight on my right butt cheek. I checked the website to see if there was a solution and checked with other using the seat. Nobody else reported the problem, and adjusting the tension on the strap did nothing. I finally figured out that it was the strap that connected the seat to the right rear post. The strap was doubled over and sewn on that side only, and when I shifted my weight it would skip over the ring and make noise. Not incredibly loud, but certainly enough to scare a deer. Maybe with my size, it wouldn't happen on the larger version, but I am not sure. Once again, nobody else reported this problem. I may eventually order the larger size and give it a go. Maybe the problem won't be there, and if it is I can make a different connection on that side or something. Overall a very well build product.
I can't imagine that there is a better chair out there, and if the noise issue wasn't there for me, it would be darn near perfect. It should really shine in a blind where you need to swivel from window to window for a shot.
