I've hunted out of an API for a lot of years, bought mine back before the company was sold. I guess probably at least 12 years. I love the way it climbs and descends. I didn't care for the seat so adapted a seat from another climber. I now own 3 climbers API, Buckshot and Equilizer. The API has the best range of trees it can be used on. It's only a pound or two more than summit or those others. I don't find it noisy except the chains inside the tubes when you walk. I shoved some foam down the tubes to quiet it. I personnally don't have a problem with the chains. You can get replacement shrink tubing for something like $10 for a set. I usually buy 2 sets at a time so I have it. Last time I had to buy it somewhere else in Alabama or Miss or somewhere like that. I'm now in my Equalizer mode so doubt the API or Buckshot will get a lot of use this year. On my API I put foam pipe insulation on the rails and taped it on with camo tabe. I padded the front part two so I could sit facing the tree if I wanted in more comfort. I like the stand.
