Poor zipper
I did not even try to use it as a cooler. Once I received it I tried to see how convenient it would be to load and unload it. I was immediately concerned with the zipper. It was very hard to unzip, and that was sitting at my kitchen counter with nothing in it. I had planned to use it on day trips on the boat, but figured if I was having trouble unzipping it on the kitchen counter, totally empty, it would be near impossible to be messing with it when loaded on a rocking boat or waverunner. I was really disappointed because the size and quality of the rest of the cooler appeared to be quite good, and the size about right for the wife and I on a day on the lake while boating and/or waverunning. I returned it without every using it. Please, fix the zipper!!
