Ok, I checked it out. I do not want to spend the day straddleing or hugging a tree. And it doesn't look anywhere near stable enough to shoot from.
If I tried to shoot my slug gun from that thing it probably spin me around

.
And I think I could shoot my bow with feet hanging like that. That would take some practice to get used to.
For that kind of money you can get a darn nice climber that is really light.
