I have an AO. My Wife bought it for me last year from the Donzi Z shop. I had no idea how much I would use it and like it. I take it on every trip I go on, both in the boat and every where else. It is great for car trips to keep kids stuff and 100% reliable.
I have had soft sided coolers before, none of them as good as the AO. I got the 24 can model, which is the 'perfect' size in my opinion.
