I bought a treewalker, and while I like the stand, their customer service sucks. I bought it at a show and after I paid for it I left it there and picked it up later when leaving. I left 2 parts I needed and I called them and emailed them repeatedly and they never got back to me until I threatened to go to the shows this and tell everyone how bad their customer service sucks. Then they emailed me right back.
All in all it's light, has the webbing seat like the old man stands do and sets up easy. I sold my summit and after a year w/o a climber decided to try the treewalker. no regrets.
