Familiarity: I've put it through the wringer
I have two of these kicking around. They are fantastic! When I was learning to paddle and swimming (very regularly) these made recovering and emptying my boat so much easier, this in turn meant I spent less time freezing on the bank and more time warm in a boat.
Now I lend them to all and sundry makes days on the river with novices much easier.
