I would really like to give this a 4.5 but that isn't an option. I have had four of these from years ago and they held up great. Eventually, one got a leak and the gel fluid came out but no complaint it lasted forever. I have only really had need of the sleeves-over time they get old and the seams come apart. When these new ones came out I was excited to get them -immediately ordered two of them. I will say they are better than anything else on the market but I prefer the old style even though it was a bit clunkier. The main reason-with the new ones the cold packs meet together on the bottom of the can, the old ones only went around the bottom of the can. The new ones have the unfortunate side effect of keeping my soda almost too cold because the bottom inch or so freezes completely . The old ones kept them cold but not frozen because the bottom wasn't covered by the cold part. So that is the half-star I removed. Also-PLEASE sell replacement sleeves. Create different colors, styles, etc... could be an additional revenue source for the company!
