Product review (5 stars): Edge star portable ice maker
I love it. It did a great job on our camping trip.  Of course it is electric. We did not have to buy any ice. I'm am not sure if it will do as we'll in the summer though. I love the ice. It is hollow inside. I think it will be alright with two bags for a day of swimming this summer. Now the camping trips in the summer it may not make as much as needed due to the temperature.  Machine is kind of heavy. And it doesn't like keep the ice frozen. You have to place in freezer to make bags and while camping once the basket filled we just but it in the ice chest. All that being said it works good.
