The Ol' Man is great. It's got the most comfortable seat of any stand I've ever used. Trust me, that's important.
It's easy to set-up and takedown. I wouldn't recomend it but I've even adjusted it while up the tree. It's that easy to use.
The only problem I've ever had is that it can't handle very small or very large trees. It's not a big deal but every now and then it matters. I'd just like a small bit of extra flexibility.
