Like others of said, most of them are made by the same company. They come in small and large. Get the large one. They do a pretty good job, and definitely will help with the cooler. We have an Igloo 32 qt cooler we use for drinks, and it will keep up in the spring and fall enough so that we only have to buy a bag of ice every third day or so, but in the summer, we have to supplement the icemaker with a bag of ice almost every day. If we had a Yeti cooler , it would probably help, but I can buy a lot of ice for the price of one of those, and they seem to grow legs ....
