Have used this kayak on 4 trips so far and have been very happy with it. I have always used the boat as a tandem, it is very stable. It is my first kayak so I can't compare it to poly or composite kayaks. Sets up in 10 minutes once you do it a few times. When filling the main chambers put as much air in as possible (A rep from Advanced elements reccomended) I use a electric pump to do most of the filling, then a double action hand pump. I have always been able to fit it back in the bag it came in no problems.
