I have had the product for 6 months (the 10-liter one) and now that the weather is getting warmer, I realized that it doesn't keep the ice at all. It's like having ice cubes in a regular bowl.. essentially, it's a container inside another one without any insulation between them.. if it had, for example, Styrofoam, it would be okay. So, for its price, it's useless. I should mention that the plastic peels off and sticks to the ice due to friction, making it unsuitable. X X X
