I had 2 different makes and they only made a soft Ice that melted real fast in a drink and watered it down.
They worked OK for putting the ice in a small 6 pk cooler with can drinks. If the cans were pre cooled.
If you went fishing for a couple hours or so
I replaced them with a freestanding Ice maker
that was mounted under the kitchen table and is feed water from the refrigerator Ice maker water line. I had removed the one in the refrig long time ago to make room for food.
And it makes hard ice(better for drinks) and keeps it hard after made. It will outlast 2-3 of the portable ones. And doesn't need water holding bins cleaned like the portable ones do.
