It's funny how we all have different opinions on products...I've taken many a nap in my API, it's the most comfortable stand I've ever used and many mornings I stay up until 11:00 or so, I'm 52 and couldn't do that if the stand wasn't comfortsble...I'm also 6ft 5 and about 250, so I can't use a small stand...

I bought my first one the first year they came out and the second about 3 years later, I've never replaced the chains, just wrapped them with camo duct tape where they go around the tree and keep using them...

There are 2 advantages of an API over a Summit...You can remove the pins that go through the chain and replace with long shank locks and lock the stand to the tree...You can also buy a padded gun rest to use during gun season, the rest that Summit used to have was a Y shaped rest that wasn't adjustable for elevation...

As far as quiet, I've had deer walk by while I was in the process of climbing the tree, I've also had deer come in within just a few minutes of getting settled in...
