We have used them for quick setups but only on 8' ladders to see over brush for varmint and pig hunting.
Just get you a couple of ratchet straps and tie the ladder to the tree and the seat to the ladder.
Works best if you strap the seat to the ladder, then raise ladder and strap to tree.
Strapping the seat to the ladder keeps it from moving and making noise - also keeps it in place.
We knocked ours off the ladder a few times when you stand up with lots of clothes or insulated suits on before we started strapping them down.
PS - if it's cold, get you a cushion as that aluminum gets COLD and radiates frigid to your butt!
